Here's something I just found that you guys might find interesting.
Dynorphins regulate fear memory: from mice to men.
Basically, what it's saying is that dynorphin, which works through kappa-opioid receptors just like menthol, is important in getting rid of fear. Furthermore, it suggests that dynorphins enhance communication between the ventromedial prefrontal cortex and the amygdala. The amygdala is, I'm fairly certain, the part of the brain that loads our schemas and creates the dream world by stimulating the hippocampus. It's also largely our emotional mind. What's interesting is that, as far as I'm aware, when it comes to the prefrontal cortex it's the dorsal part that shuts down during regular, non-lucid dreams (and presumably reactivates during lucids), while the ventral part stays active, and the dorsal PFC is responsible for rational thought while the ventral PFC handles emotional thought. That's why in a regular dream emotions can be so intense without any logical input, and this would suggest that dynorphin enhances that. In addition, the amygdala has been implicated especially in aggression, sexual behavior, and euphoria (in relation to things like depression). Definitely the first things that come to mind are (a) the dark themed dreams/nightmares of menthol particularly like in the thread that spawned this one, (b) the sexual dreams, of course, and (c) the pure happiness dreams that Kaomea experienced. Couple that with the loss of fear that would translate into more confidence, and it seems to pull together well for me....
Anyway, that's all I can say for now, I need to head out!
