Okay I know this is going to sound dumb and you might think I sound crazy but I swear it’s true! So earlier I was working out in my basement and I got off the treadmill and walked over and started lifting weights. Well in my basement we have this spinning bar stool chair and when I was on the treadmill it was facing like in b/w the treadmill and the bike. While I was lifting weights I looked over and I swear the chair moved (like was swirled around facing me) and I thought maybe I was imagining things so I stared at it seeing if it would move and it moved a tiny bit! I got so scared and went upstairs and told my dad but he said yeah right I’m probably imagining things, but I swear it moved! Do you think it could be a ghost? Or my grandma (she passed away about 5 months ago)?
