I was watching Ghost Travelers or something like that on tv a couple nights ago when they had said "Do you hear that, it sounds like something dragging". About 3 minutes after they said that I heard what sounded like a soda can sliding on my kitchen counter which was right next to the couch. I timidly looked to see if there was a can but there wasn't then was scared to see my cat staring at the wall in the kitchen right where i heard the sound! He kept looking up and down about 5 times. I looked to see if maybe there was a fly or something but there was nothing. I'm sure it was some kind of spirit and boy was I scared after that!!
