I’m surprised I’ve never had a dream like this, but there was a children’s doll stalking me. I had no problem smashing it to bits, but killing it resulted in another doll let loose against me.
I was doing other things in the dream, but there was this constant threat of killer dolls. Each time I killed one, another would replace it.
At one point I thought I was done killing dolls, but I was outside at night and I turned and saw standing in the middle of the street two disembodied doll legs and a doll head sitting beside it. They had found me and were ready to attack.
I think I may have sighed and reached for something to kill them with, like a 2x4 or a baseball bat.
