Did anyone else have weird "fetishes" as a young child?

I remember being eight years old and getting erections from the thought of magically shrinking, like in a cartoon.

I'd try to stimulate myself by hanging myself by the pants onto my bedroom doorknob, and ride my door into walls. I'd do this pretending I'd been shrunk and was having wild adventures.

Another thing that gave me erections when I was 7 or 8, was by crawling around with a plastic laundry bin stuck to my back. I'd pretend I was a turtle.


Is this normal? Why did these things arouse me? I hadn't even hit puberty yet or developed any actual sexual feelings.
