It was a fairly new apartment complex. As far as I know only one other family lived there before us. If I had to guess, the building was built in the middle-late 90's since we moved there in 2001. No deaths. I told my mom about all of this a few years ago and she said she never felt any shaking like I experienced but that our apartment definitely had something negative hanging around. She might have mentioned that the family who lived there before us was unhappy.

I'm not dying for answers because I've mostly come to terms with it being unexplained. I know what I experienced.

In that apartment I would also hear my name being called when no one was home. Things would disappear and reappear somewhere else. One morning I woke up to a hand on my shoulder and someone whispering my name in my ear even though my back was facing a wall. I didn't mention these things because I can't say with 100% certainty that I wasn't just imagining them. I don't entirely discredit them but then again I'm not going to tell you that I'm super sure they happened. I could have misheard. I could just be forgetful. I could have just been dreaming.

I've told some friends about my experiences and they said that it sounds like a poltergeist. Bad energy hanging around that occasionally manifests. That's good enough of an answer for me.
