yea man u need to do something. otherwise...if thats in your dorm and you don't have anywhere to go...thats a health hazard bro.
Get it checked out/reported and fixed ASAP.
Mold spores can cause cancer


you need to tear that drywall out. Another thing is to encapsulate that stuff. Repaint it with a moldicide paint.get that fan fixed asap. Did you check it? alot of times they are just unplugged. If if your going to replace it, get the largest cfm fan that will fit in there.
And clean with a product made for mold.
Honestly, mold is bad. if thats the Stachybotrys kind, I would not stay there.
see if your fan is unplugged. if not get one, they are like 15 bucks to replace. Run it 24-7. and just paint it with a moldiciede additive added to the paint. Nobody but you cares... so you gotta deal with it .. How long do you have to stay there? if its 6 months or less, I wouldnt worry about it and let the next person deal with it. Mold will and can cause lung issues.
Spaying bleach is just as bad. May even want to put a dehumidifier in there, but i bet that would just mold up too.
1. but mold cleaner/paint.
2. fix fan
3. nail the door shut and shower somewhere else.
