Okay, this is something that happened to me, not both of us.
It was in the same house in Morenci, in my room.
I was sitting at my computer, just playing games and listening to headphones. All of a sudden I feel as though someone kicked the back leg of the chair. I swung around and....nothing. Creepy. Like, 30 seconds later, it happens again.
I had to leave the room.
Keep in mind, my chair DOESN'T have back legs. Just the way it's built. It's a metal chair and it balances on the front legs.
I tried to debunk it and if you kick the part it rests on, on the ground, you can't feel it. There's no way it could've been the front ones either.
That's one experience that's always stuck with me.
