Last night I was standing in front of my sons door with my back to my bedroom door. All a sudden I felt something cold on my arm and I looked out of the corner of my eye at my daughters room. I thought I saw something or someone go into my daughters room. When I looked fully into my daughters room no one was there. And several times I have seen a shadow of someone in various rooms of my house. I always feel like someone's watching me. I want to know if its just my imagination or if my house has ghost. I was so scared I didn't go to sleep and I stayed in my sons room with my kids with the door shut all night.

It's possible that there is a spirit in the house. Why not try setting up some video and audio recorders and see what you come up with?
