I wish I knew how to switch on this power. As it stands, I seem to be pretty good at grasping the abstract “shape” of problems, in a way that short-circuits words, but I can’t flow forth with conversation or write believable dialogue to save my life. My thoughts are entirely fuzzy.
Sometimes when I’m very sleepy, I can simulate friends and relatives talking to an uncanny degree, but not at any other time.
I know I'm falling asleep when the movie of thoughts and images playing in my head becomes more like watching something play out on its own than thinking it myself. The thoughts and scenarios stemming from myself become more vague and start to come from somewhere else, basically transitioning from inner-monologue narration of images to compiled dreams that I no longer have control of. However, if I think about my own falling asleep as it's happening the self awareness wakes me up.
I don't have "movies of thoughts and images playing in my head" in waking life, but I do start having visual dreams. But I've only once been able to actually observe them beginning, usually I just wake up in the morning with no memory at all of the transition.
