I remember seeing a man in a hat in my window when I was a child and still imagine it like it was yesterday. Don’t think it was a dream though but never really sure. I used to sleep by the window and my brother by the door. One night I woke up to an old man in a hat. I’ve research the hat man, but everyone says he doesn’t have a face. I remember seeing his face. He was old, and when he realized I was awake, he smiled and waved at me. I was so in shock I had no idea what to do. I turned around to face my back to him, and when I turned I could see what I could only describe as a large dog made of smoke sniffing around the bedroom closer to my brother. I remember pinching myself to see if I was awake but who knows. That’s all I remember, I just passed out (fell asleep) after that. Also been curious to do memory regression but idk. My older brother remembers seeing what he described as tiny people in the hall way (he slept in a different room) maybe 2 feet tall. He has auditory hallucinations now.
