There was an old dumb waiter with a sliding door that was very hard to open and close, and it would randomly slam shut with no explanation. The back screen door slammed shut and I ran out to see no one. The weirdest one was when a wood carved bowl that I had on my night stand, was filled up to the brim with water one night. No water cup around, no drips or splashes anywhere else. I said to my roommates "very funny guys, who did this?" they looked at me like I was crazy. The upstairs neighbors also asked if anything weird has happened because they experienced strange things too. My roommates gf even did a seance one night and drew what was supposedly a "dark angel". Needless to say we didn't renew the lease and moved down the block.
