Purge all mainstream people from your life, go it alone for a while if necessary.
Eat coherent nutrition.
Rest in pure awareness as much as possible. (no thought).
Begin to examine everything freshly and with no connection to past memories (remove filtered thought).
Engage in practices to sharpen focus (3rd eye). There are many shamanic practices that do this. One practice is to imagine running without your focus wandering. Toltecs used to do this.
The end goal(within the story construct) would be to have unfiltered clarity while having the ability to project a reality of your choice, crisply, and with exacting coherence.
