So my room mate sleeps in the basement..... When he first moved in everything was fine but now his pillows have this slimy coating on them. We checked the walls, ceiling, everywhere but cannot find the source.... Does anyone have a possible idea as to what it could possibly be? Oh and he's also had stuff literally disappear on him.... He would set an object down (piece of clothing, toiletries it doesn't matter) he would look away for two seconds and when he turned back that object would be gone
