I myself have encountered two men in my bedroom one night. The lights were off but you could still see about the room. In the corner I saw two men ... but only from the thighs up ... talking to each other. I could see their profiles and their moving and gesturing. I could not hear them. I studied them seriously and then they both looked at me and then started talking among themselves again. Eventually they faded out. It was amazing!
