Creepy Dolls

This is something that I just remembered, actually. This happened when I was twelve, and it happened in my bedroom (the bedroom that I still have. I have always been really scared of dolls, ever since I was six years old and saw a horror movie about dolls coming to life. But, even though I have a vivid imagination that can sometimes freak me out, I know that I was not imagining this: Like I said, I was twelve years old, and it was in the middle of the night, and I had just gone to bed.

Under my bed I had a big box containing this doll (the Amazing Ally-doll) that I used to play with when I was nine or ten (yes, I played with dolls when I was little but I played with toy cars and action figures as well and I still hadn't put it away in the attic, so it was still in its box under my bed (and since I was so scared of dolls in general, I had put silver tape all around the box... I know, I'm paranoid)

That night when I was trying to sleep, I suddenly hear the doll turning on under the bed! I hear the creepy Ally doll saying "Hi My name is Ally! We're going to be best friends...blablabla" (it was the same thing that the doll always said every time it was turned on) and I just lay there, paralyzed, as I heard the doll speaking. Something that scared me even more was that, the next morning when I took the doll out of the box, I discovered that there were no batteries in it at all! That day, I got rid of that doll forever.

So what do you think about it? Do you think someone/something was just messing with me, or was it something bad?
