Well, this is a story from my mom, but its the first time ive ever seen anyhthing. During this time, we were staying at my grandparents house, and my mom was gonna go give me a bath before bed, (I think I was 2-3 yrs old at the time) but before that, she went to go lock the door, leaving me on the stairs. When she was walking up the stairs, I just stared behind you and said, "Theres a man behind you..." but when she looked behind her, she saw nothing, and was like, "What are you talking about?" and continued to walk up, but I was still like, "Yeah, behind you." but she was so scared of what I was saying she just grabbed me and ran up the stairs. I still see shapes like that sometimes, like I see someone sitting next to me, or walk past me.
Ive seen other stuff too, and much worse, if you want to hear it. But ill stop here for now.
