I'm not afraid of dolls, but I don't think I especially liked them much as a child. I had one or two baby dolls, which I played with occasionally.
I did have one rag doll type of doll when I was very little, she was cloth with yarn hair and had a soft rattle inside of her, and she and I were inseparable. When my mother put her in the wash, I would sit in front of the machine waiting for her to come out.
When people gave me Barbie dolls, however, they quickly found their way to the bottom of my toy chest.
I, too, have tons and tons of stuffed animals. I've always preferred stuffed animals over dolls. Of course, I also prefer real animals over real people (is this your case as well, animallover?) I now also make stuffed animals, which is quite a lot of fun. I love the tactility of them. I also liked to play with my little brother's metal matchbox cars, and have a good number of my own, as well.
There is some kind of scientific law (sorry, I can't recall the name) which states that the closer something gets to being human without actually being human, the more off-putting it becomes. This principle is being applied to AI, especially those researchers who aspire to create life-like human-like machines (like in science fiction movies). Essentially, unless they can make it look exactly like a human, they will stay away from creating something that is close, but not quite there.
I don't think it's just an AS/autistic thing to be afraid of dolls, because there are many stories and movies about evil dolls coming to life. Automatons, dummies, baby-dolls, and androids, it's all basically the same principle- something mimicing human form which takes on human characteristics (movement, personality, etc) undermines what it is that makes us as humans unique, in our minds. It makes us question how real and human we really are. I took a class on Gothic Literature and film last year, and this was one of the major themes in the class.
I don't know if that's the same reason why autistics are afraid of dolls, but I thought it was interesting information, so I figured I'd share it .
