Caleb Wilson saw dark shapes growing on the bathroom wall. These were not common water stains or mildew. Mushrooms, real fungi, grew straight from the wall surface. They stretched 4-5 inches wide.
Caleb didn’t realize these mushrooms pointed to something worse than a strange science project. Something looking like a simple bathroom invader signalled serious structural damage hidden inside his student housing walls.
Ancient wisdom across cultures links physical cleanliness with spiritual wellness. Many spiritual traditions view our living spaces as mirrors reflecting our inner states — a principle supported by modern research on environmental psychology. Just as meditation clears mental clutter, maintaining clean physical surroundings allows positive energy to flow freely through our spaces and lives.
A curious Reddit post began the story. It soon uncovered a dangerous problem, possibly spreading beyond Caleb’s bathroom to his whole building.
Sharing More Than Just a Bathroom
College housing offers students independence but also unexpected challenges. Many undergraduates, balancing classes, social activities, and part-time jobs, fail to notice subtle changes in their living spaces until problems become apparent.
Maintenance issues in student housing often go unreported for weeks or months. Buildings housing hundreds of residents face constant wear, with bathrooms proving particularly vulnerable to moisture problems due to daily showers, poor ventilation, and aging plumbing systems.
Caleb Wilson, a sophomore at Westfield University, lived in a six-person suite with shared bathroom facilities. During midterm week, while rushing to prepare for an economics exam, he entered the bathroom at 6:30 AM. He spotted something unusual growing from the corner where the shower stall met the exterior wall.
At first, he assumed someone had dropped something dark on the floor. Upon closer inspection, he realized these objects were emerging directly from the wall. Unlike typical bathroom mold, which appears as dark patches or spots, these growths had defined shapes with stems and caps—unmistakably mushrooms.
Guess What Popped Up in the Dorm Shower?

Caleb observed that they resembled small ink cap mushrooms, with narrow stems supporting dark caps. Most alarmingly, they seemed firmly rooted into the wall material itself, suggesting whatever was feeding them lay beneath the surface.
After his initial shock wore off, Caleb did what any digital-native college student would do – he turned to social media for answers. His Reddit post included clear photos capturing the bizarre bathroom invaders along with his worried query: “Found this growing in my university shared bathroom! The growth spans around 4 to 5 inches. Does anyone know what it is and if I will be dying???”
His post immediately caught attention, racking up comments within minutes. Fellow students shared similar horror stories, while others offered humorous takes on his predicament. A few commenters with knowledge of biology, however, recognized something far more concerning than an unusual bathroom oddity.
What Caleb had documented wasn’t just a strange biological curiosity – it was visual evidence of a significant problem lurking inside his dormitory walls.
Caleb’s Fungi Photos Stun the Internet
Caleb’s mushroom post quickly went viral across campus-focused Reddit forums. Users responded with a mix of horror, humor, and helpful advice, turning his bathroom fungus into an overnight sensation.
Many comments leaned toward apocalyptic scenarios. One popular response declared: “This is how The Last of Us s*** starts,” referencing the popular video game and TV show where fungal infections create zombie-like creatures.
Another user named siqiniq joked morbidly: “The missing student on campus who was never found 5 years ago,” suggesting something sinister behind the wall.
Lumpy_Promise1674 provided a concerning analysis: “The wall is not built right. Probably a major code violation, but it’s not my area. What you’re seeing is only the fruiting body of a fungus growing inside the wall because they didn’t use the proper materials and building techniques for a room with showers. Probably insufficient ventilation, too. Cleaning has nothing to do with it, other than removing the fruiting bodies when they appear. Yes, this is bad for your health. Hell, this is only the one species that you can see. Who knows what else is in the walls and vents. The worse news is you probably won’t have access to this bathroom for… well, likely indefinitely. I would not be surprised if they pay someone to gut the bathroom and then seal it until they can drag enough budget away from administration bonuses to pay for a remodel.”
Muted_Support_605 shared a similar experience: “these grew in my bathroom ceiling once. the mushrooms burst and purple juice spilled out so i called a plumber and he gutted the ceiling. pulled out tons of trash bags and old mcdonald’s bags. turns out the workers who renovated the apartment before i moved in threw all their trash in the ceiling and then sealed it all up. plumber said he saw this all the time (i live in nyc). nice apartment otherwise tho”
Try-To-Support-78 advised skipping minor channels: “skip the RA and report it to the dorm head… let him/her know you already posted it to Reddit but you’re concerned about not only yours but everyone’s health… i doubt you will die if you aren’t in direct close proximity of breathing the spores. There was a outbreak in the “dorm” here at Ohio State like about 2-3 years ago… It really an apartment complex the uni took over and probably didnt even check for mold, but it did get on the news etc. I mean you dont have to threaten them to take it to the news however….”
Murky_Shop6887 added comic relief with their story: “I had this happen to me in my apartment. When I emailed my property management they didn’t believe me when I said I had mushrooms growing in my bathroom. The maintenance man came in and was stunned that I was telling the truth, and even took a picture to show to his friends. It was funn,y but yeah, he spent about a month in my bathroom replacing the walls. It was so nice when he left so I could go to the bathroom in peace and smoke weed in my home again.”
As comments accumulated, one response from a verified mycology enthusiast caught attention. Unlike others focusing on jokes, this expert recognized a much more serious problem lurking beneath the surface—one that would fundamentally change how Caleb viewed his living situation.
How Does This Nightmare Even Happen?
Several common water entry problems probably caused mushrooms to grow inside Caleb’s bathroom walls. Student housing often faces these issues.
Burst pipes are a top reason for water damage in campus buildings. Many university dorms have old plumbing systems that were put in years ago. Pipes slowly wear away, get tiny leaks, or break open completely. Cold winter weather sometimes makes water inside pipes freeze and expand, causing breaks. A small wall leak might pour gallons of water each day before anyone sees the major damage.
Bad waterproofing jobs fail to keep water out of bathroom walls. Shower areas need special seals behind tiles. These seals stop water from moving into the walls. Many cheap building projects or updates skip these needed moisture barriers. Skipping them lets water get into wall structures with every shower.
Roof leaks significantly increase wall damage in top-floor dorm rooms. Water gets in through harmful roofing materials and travels through the building, often far from where it first arrived. Students living upstairs might see water damage from roof issues instead of bathroom leaks.
Poor airflow makes moisture problems worse throughout the dorms. Weak bathroom exhaust fans do not effectively pull out shower steam. Moisture then condenses inside wall spaces. Condensation creates ideal spots for fungi, especially in buildings without enough insulation.
Plumbing stack problems create very troubling situations in buildings with multiple floors. Main drain pipes going up and down through buildings can crack or leak at joints. Cracked pipes leak dirty water into nearby wall areas. Leaks like these make places especially unsafe where fungi can sprout.
Clean Spaces Nurture Clear Minds
Many ancient wisdom traditions acknowledge powerful connections between our external environments and inner states. Maintaining clean, organized living spaces goes beyond merely looking nice—research suggests our physical surroundings directly influence our mental, emotional, and spiritual well-being.
From a spiritual perspective, caring for your physical space becomes an act of self-care and mindfulness. Each cleaning action—dusting a shelf, arranging books, or sweeping floors—transforms into a meditation opportunity when performed with awareness and intention. Physical organization mirrors and supports inner clarity.
Energy flows differently through organized versus cluttered spaces. Ancient practices like Feng Shui recognize stagnant energy accumulates in messy, neglected areas. Clearing physical blockages removes similar blockages from our mental and spiritual channels.
Sound frequencies also affect our spaces and consciousness, as explained in Dr. Emoto’s research on water crystallization patterns. Our environments constantly broadcast signals our bodies receive and process, often subconsciously. Much like radio signals reaching receivers, external frequencies impact our internal states.
Simply putting away items after use creates ripple effects in consciousness. Each small act of order builds habits transferring into greater life aspects—relationships improve, work flows better, and spiritual practices deepen when physical environments support rather than hinder our growth.
Making small, manageable changes proves most effective for lasting impact. Start with one area—perhaps your meditation space or desk—and notice subtle shifts in how you feel when occupying clean versus cluttered environments. Gradually expand these practices throughout your living areas while maintaining awareness of corresponding internal shifts.
Found Fungi? Your Urgent Next Steps

finding mushrooms on your wall definitely means you need to act fast. Wall fungi signal a bigger water problem hiding behind the surface. Ignoring this can cause property damage and affect your well-being.
Why Wall Mushrooms Are Bad News
Mushrooms growing indoors suggest excessive moisture is present. Damp conditions allow mold and fungi to grow. Breathing in spores from indoor fungi can cause breathing problems or allergic reactions for some people. Plus, moisture weakens wall materials over time.
Keep Your Distance For Now
Do not touch or try to remove the mushrooms right away. Disturbing them can release spores into the air. You want to limit your exposure until you understand the situation better. Keep children and pets away from the area too.
Find Where Water Is Coming From
Your main job is locating the source of the dampness. Check for leaky pipes inside the wall. Look for roof leaks dripping down. Consider condensation building up from poor airflow. You must find the water source to stop the problem.
Stop Water Leaks Pronto
Fixing the leak is step number one. You might need a plumber or roofer, depending on the water source. Simply removing the mushrooms without fixing the leak means they will likely grow back. Stop the moisture supply first.
Get Rid of the Mushrooms Safely
You can tackle the visible fungi after fixing the leak and letting the area dry somewhat. Wear protective gear like gloves, eye protection, and an N95 mask. Carefully scrape the mushrooms off the wall into a garbage bag. Seal the bag tightly before disposal.
Clean Up Thoroughly
Clean the affected wall area using a suitable cleaning solution. A mix of detergent and water often works. Some people use diluted bleach solutions, but check if it’s safe for your wall surface first. Always ensure good ventilation when cleaning. Dry the area completely afterwards, perhaps using fans or a dehumidifier.
Call in Help When Needed
Dealing with widespread fungi or a persistent moisture issue might require professionals. Mold remediation specialists have the equipment and knowledge to handle large problems safely. A building contractor can help if structural repairs are necessary due to water damage. Don’t hesitate to get expert help for serious situations.
Spot Hidden Wall Problems Before They Sprout
Caleb’s bathroom mushroom problem warns all college students living in shared housing. You need ways to spot early water damage signs before serious structural issues develop.
Musty smells often give you the first hint of hidden moisture. Notice any lasting damp odors, especially in bathrooms, kitchens, or near windows. Your nose frequently finds problems before your eyes do. Look for discolored patches on walls and ceilings. Water entering the structure causes yellow or brown stains. Check out even small spots; water can travel quite a distance before you see damage.
Touch wall surfaces often, particularly after it rains. Drywall that feels soft, crumbly, or bubbly shows that water got in and damaged the material. Walls ought to feel firm when you press on them. Keep an eye on peeling paint or wallpaper because moisture lets the glue go. Spots where coverings pull away from walls frequently point to water trouble underneath.
