Not necessarily creepy in the sense of scary just really weird to me. This story is from my mom. When I was about three years old I was chilling in my crib in my room with the door about half open, and I was alone. My mom was with her friend in the dinning room probably twenty feet away. They were having a conversation when all of the sudden she can hear me talking. She can’t make out what I’m saying only that it sounds like it’s a conversation. She comes down the hall to see what I’m doing. When she peaks her head in she sees me standing up holding onto the edge of the railing looking behind the door. She asks me what i was saying and I told her was talking to Poppy, my grandpa who had died months after I was born. All I knew at that age was that he was my grandpa. She said she could feel herself go pale and she asks what we were talking about. I tell her he was telling me who he was and that he missed us all very much. The things I was telling her that he told me were impossible for me to have known about before hand. Nothing crazy like the solution to pie or anything like that, just information about himself and our family. She asked me where he was standing and if I could still see him. I pointed to behind the door and that no he wasn’t there anymore. That’s pretty much the end of it, fast forward to now and I have no recollection of that at all and I’ve never had an experience like that since. It freaks me out every time I think or tell someone about it
