To hear someone running upstairs while home alone.
So A couple days ago I was home alone and I heard what I thought was my cat running around crazily upstairs, so I payed no mind to it. And then I heard a thud upstairs like he knocked something over and when I went to go check on it I realized my cat was sleeping in his bed behind me the whole time.
I kind of froze because I immediately thought someone has to be in my house. So I got a bat from the basement and started heading upstairs and checked every room out and nothing, no one. I didn't even notice anything had been knocked over or out of place. It just made me more scared so I just screamed get out of my house or I'm calling the cops. And then I ran downstairs and waited until someone got home.
Ghost or what? D:
