My earliest memory of anything horror is my ghostly experiences that started around second grade, from what I can remember... Seeing a black glass object slide across a floor at me, and then seeing a misty character in an abandoned apartment.
I have had paranormal activity happen around me since I was young. Most of mine come in dreams though. I could go on with the vivid dreams I had for hours, but the ones that really scared me were the ones that left me waking up in the real world suffocating. I've seen objects move, swing out of nowhere, heard voices, and seen doors slam. Unfortunately, they have kinda numbed my scare senses, and it takes a really good horror movie to finally give me the creeps.
