Same with me every night. I feel that I am secretly being watched somehow, even though there isn't anybody in the room.
Time for a story. So, at my old house, maybe about 5 years ago, I was getting ready for school on a normal day. I was about... 10 at the time and I wasn't really sure ghosts existed. I had sometimes been afraid of the dark for no apparent reason, and I would always try to get out of dark rooms as soon as I could. After I had ate and gotten ready by brushing my teeth and all of that, I went to turn out all the lights in the house to save energy. I went in my parents bedroom, and the light was already out, but what caught my eye was a transparent bodily figure floating and running across the room. There was no one I the room, so I ran out, shut the door, and ran downstairs.. When running down the stairs, I swear I heard some scratching in the bathroom right next to me.
That's pretty much my ghost story, but I honestly am not sure if I believe in ghosts.
