Okay, here is my other story. It's not a 'what the heck was that thing' type, but it is a scary story. We know very well what the 'thing' was, it was a possessed doll
When me and my sister were small, mom and dad bought each of us a life-sized doll. I remember them being called 'walk with me, talk with me' dolls, but I can't seem to find that online so apparently it's not the right name. These dolls were about 36" tall, had voice boxes (pull string on their backs), and had a rubber band thing inside their 'hips' that allowed them to 'walk' with you by holding their hands. Of course when we first got them, my sister and I loved them. I think we were either 5 and 6 or 6 and 7. Either way, we were pretty young.
My cousins didn't help matters any, they'd always tell us stories of their dolls pushing them out of their beds and such. I remember seeing a movie about dolls like this (the dolls were real children) that came to life and started killing people...Obviously, young girls shouldn't watch movies like that, but we always tried to 'sneak a peek' at the scary movies dad and my uncle were watching when we visited.
Anyway, we got so scared of these dolls that we locked them inside our closet. It was so bad that if we went to bed with the closet open we would scream bloody-murder until mom or dad came in and closed the door. I'm sure my older brother probably had something to do with our being so scared, because I remember a few times waking up in the morning with the closet door open and having dreamed that these dolls had been out during the night. Then of course there were times when we woke up (sister and I shared a bed at the time) and one or both dolls were either IN the bed with us or lying on the floor beside the bed. I'll blame most of this action on my brother, though I don't know for sure and can't ask him. But it is something he would have done.
Okay, now to the story. My brother had moved out, sister and I were probably 13 and 14 years old. We now had a 'new' sister who would have been about 5 or 6 at the time. For some reason, we'd had one of the dolls (the other had disappeared? I don't remember what happened to it) out in the living room with us, it was sitting on the couch. I think baby sis liked to play with them and since we were 'older' we tried not to show our fear of this doll. Anyway, one night me and my sisters were home alone, mom and dad had went somewhere and brother had moved out. We heard the dog outside raising Cain about something, so all 3 of us went outside to check it out. I don't remember if we found something, I think a raccoon or opossum was out there...anyway, we turned to go back in. Now, mind you, when we went outside the doll was sitting/laying on the couch. I know for a fact it was not moved because I was the last one out. When we turned to come back in, the doll had moved about 10' and was sitting in front of the door....
Now, you tell me how that doll got there? It wasn't brother playing a prank, and none of us had moved it. There was no one else in the house, and we know it had been on the couch.
Needless to say, we stayed outside until mom and dad got home. A few years later dad finally took the doll and burned it after it had been locked in the front porch closet. I guess since baby sis was now terrified of it as well he decided it was time to get rid of it.
