If you feel like sharing, I'd love to hear more about your experience with this.
But that initial "boom" when you go from "i am me and i am here in my head" to "oh hey, i have an invisible counterplayer in here that is capable of manifesting itself as realistically behaving, voice-pitch-perfect impressions of all my friends and family, who proceed to harass/cajole/support me in a theatrical landscape choreographed with split-second focus on whatever it is my "i" express." Granted, this is also dream, but dream is too fragmented, and too prone to halt|flush|restart compared to four/six hour long internal conversations (with the occasional external auditory hallucination when fitting).
And then you get to live that for a few years, and its a mixture of exhilarating and scary as fuck. And you're forever left with a brain that you sometimes think of with the premonition "well, if you could do that, what other tricks do you have up yor sleeve".
