>>21282106you're almost right
the processes of intuition building (within the context of an existing civilization) and socialization (within the context of an existing civilization) creates a patterned and organized set of expectations and behaviors in the average person
ALL brain dysfunction can move you outside of these sets of expectations and behaviors
very drunk people, people with infections (like urinary infections which pass the brain barrier), drugs, any number of outside agents like parasites, physical destruction, improper development in the brain, the list is enormous. even the development of additional personality nodes (this happens more than you think, ventriloquists are often completely insane by therapeutic standards because they've developed one or more additional personality nodes)
even strong beliefs can cause brain dysfunction by modifying behaviors outside of norms
drugs don't free your mind, they break your rigid learned system of self control, and for some people that is a revelatory experience, and for others it is completely destructive, and a broad range in between
