Ive been thinking alot about the hard problem of consciousness and how electrical information in your brain correlates to experience and the feeling of being able to "watch" your own thoughts and actions. My best guess is that awareness is a type of program designed by evolution to make the primary decision making processes connected to most logic enabled and highest complexity structures in your brain, so that you make the best decisions in the interest of your genes. Subliminal stimuli is a thorny issue because it means there is alot going on in your brain that you are not aware of.
Im interested in how certain psychadelics can alter your consciousness and affect your percieved experience in ways that are not encountered sober.
Hopefully it might shed some light on the problem.
