Hi Geoff,
Welcome!
I don't believe other people can really interpret dreams for others very well--there's too much personal symbolism that goes into a dream.
However ....
...
All the math you're taking may not stall your OB interest --it might even increase it, since the brain / mind/ soul is much more than the rational exercises we so often give it.
So I agree with your second post that your 'unconscious' or whatever is trying to get your attention about the reality of dreams and other non-physical/ OB experiences.This dream has used at least 2 ways to get you involved:
It told you that your friends are involved in the reality of dreams. Your friends don't have to be friends you now have. They could be friends from your way past or your future. They have discovered wonderful treasures in their dreams to take back to waking life, symbolized by chocolate or hunkiness. Great symbols!
Also, there is a 'hook' to catch people and get them more involved with OBing that is not discussed much because most people get too hung up on it('Hook' as in fishing--to catch with): You can do OBs where you meet souls that are pure energy and do 'soul melds' with them. Soul melds are an exhilarating experience! The closest experience most people relate them to is sex, but while OB the entire energybody melts and blends with energies of another, usually someone of the opposite gender.
It's just a stage in spirit. These will lead you to understand the unity of all, not just a specific partner, and also lead to further understanding of the unity of all life, time, and space beyond the categories we put things in. People who get too attached to this stage eventually lose energy, it seems, until they can get back into making spiritual progress.
My guess is you put these potential partners in black because it's such an unknown hidden fact, or perhaps in your country you also have guilts about how to deal with the opposite gender, as do most. And if you don't currently know a Jannie, then I'm betting you're going to meet her. Because our dreams lead us through our lives; they can be prophetic.
Despite your studies, if you can find an uninterrupted time to take a nap when you're not completely tired out, I suspect you'll learn and experience alot more! Congratulations!
