I was just thinking about when I first moved into my new apartment and I was convinced it was haunted. I would hear things all the time and swore I heard my roommate laughing when she wasn’t home. I was also so paranoid when left home alone that I had to barricade my door to fall asleep or I would do “sweeps” of my apartment because someone somehow broke in. Then it all magically went away after I went on medication lol. Like I would get terrible paranoia that would come and go in phases, it makes so much sense.
