Another thing to consider is an informational sensory fast. Shamans call it the dark room. You lock yourself into a fully darkened room or a suite. You use ear plugs and eye mask and you don;t make any sounds. You stay in the place for a few days.
What will happen is similar to what happens in a deprivation tank. Your own mind will begin to hallucinate and give ques of what operating patterns one is running. They will be dream like and metaphoric.
Some people should not try this without help and supervision.
