Why do I feel as though I'm being watched and glared at, and had a dream about a scary ghost?

Well, I sometimes feel like I'm being watched...always felt that way, but only at home. I've heard people say that I'm just paranoid or it's only because I'm thinking about it. But it happens when I'm most relaxed and when I'm not thinking of anything but even just LOL-cats...and the dream, was so vivid...it looked exactly like my house. It started in the laundry room, I was folding rags and towels. I had noticed a rag I folded had moved toward me, and I put it back, but it just moved back to where It moved itself. I looked at it, puzzled. It started moving toward me slowly, I backed off, feeling what I feel when I feel I'm being watched. The great evilness of the demon eyes glaring through my soul, an unsettling feeling. I slowly backed away, and then eventually started to run. i was near my living room when I turned around to see if it was still there, even though I couldn't see it, but I could feel it. It pushed me down into the dog bed and before anything else, I woke up, panting in a cold sweat. Along with being watched, where I feel the glare coming from, I can rarely walk through without being scared. Any ideas on what this could be?
