I believe that crossdressers have a higher developed sense of self-reflection and cognition. We examine ourselves and ask, "why?"
The area of the brain controlling conscious cognitive processes is the anterior prefrontal cortex, and this is larger in people with a higher developed sense of self-reflection (metacognition). This same area of the brain is also associated with people who are capable of lucid dreaming.
So my question is, do you have lucid dreams??? Do you have some dreams where you aware you are in a dream? Are you able to control parts of the dream? Regarding myself, Yes, I have some dreams where I am aware I am dreaming and I am able to fly and control parts of the dream. I wonder if this is a common in the crossdressing community.
