When I was very young, around 5 or 6 yrs old. We lived in projects in Alexandria La. I had to stay at a babysitter's house alot, she had 3 kids of her own. I was really good friends with her oldest daughter who was a yr or 2 older than me. Alot of the time we were left alone at nite there, her oldest daughter to watch us. But since we were kids, we would turn off the lites, play record player, just running through house playing, being silly. One of the things we would do, was there was this spot in there hall in the corners, that if you put your back to them you would slide up the corner, kinda like the feeling abit of a gravitron (the carnival ride) at the time it didnt scare us or anything. I thought it was normal as a kid bc we were all doing it. I didnt really realize that it was strange until i was an adult and i was telling my husband about it..
