I'm obsessed with dolls because I've always dreamed about being shrunken down to the size of one.
That's odd. Why do you dream about being shrunken down to the size of a doll?
At that size, I feel more in control with myself.
That seems strange to me. I think you should face the world as it is and not fantasize about things that is impossible to happen.
How do you know it's impossible?
Because no one has been able to do it. Humans cannot change their body size that way.
