Hallucinations. Two days ago I saw a hand floating 6 feet above the bed. I was walking out of the bathroom and just heading downstairs and right in front of me I saw it I was panicked for a while thinking someone was in my house but no one there. I do not believe in ghosts and am a person of logic so I know something else is going on. Today I was in the bathroom and I saw something like snow falling to the floor. I looked up to see if it was something from the ceiling falling down but nothing was there when I looked down there was no residue. I have been hearing noises like a thump or a fall or other strange noise every once in a while but nothing there to cause the sound. Smells that aren't there like cooking of food. Sometimes blankets moving or something sitting down next to me almost like an animal such as a cat or dog or rubbing against back or side. There may be other things that I do not notice but it feels real and quite vivid and very unnerving.
