the other day I was sitting on the couch across from my parrot's cage. Out of the corner of my right eye, came a black smokey shadow, followed by a smaller black shadow. They seemed to go into the bird's cage and disappeared. Then the following day, sitting on the same couch, I heard indistinguishable voices in my bedroom when the shadows first originated from. The following day, I was in bed and felt the sheets next to me being pulled down and somone or something got into my bed. When I turned on the bedroom light, the pillows on the other side of the bed were re-arranged. It scared me because I don't know what this is all about.
