Interesting, do you think geomancy could help or how do you plan to do this?
The principle is relatively simple. The method is two-fold: achieving lucid dreaming with consistency so dreams can be consciously interacted with with a degree of awareness conducive to my goal, and utilizing basic manifestation to focus on the intention of having a very particular dream where I am a reading a book I'm actually reading in my waking life and simply picking up where I left off. This may or may not function as desired, and it's up in the air if I can conjure information I've never read or heard about before within a dream accurately.
I am developing a method that should hopefully make my manifestations substantially more focused and concentrated, and thus produce much more precise results. But, I'm just returning to this after a short hiatus. I'll get back to you once I've gotten that method established.
I'm afraid I don't much of anything about geomancy, so I could not tell you if it would aid my efforts.
However, even if my primary goal (reading information I've never encountered before accurately within a dream state) proves unattainable, I think you could still utilize this method to perform mathematical operations, or even to reread something you have already read before, so it would not be completely useless.
I'm primarily doing this because I have a very busy life, so any way to eke a few more hours out of the day for my magical studies would be a gigantic boon.
