i've had times (where i took lots of psychidelics) where my subconscious, or what i think is my subconcsious, was like some overseer for everything that i was seeing and experiencing. I could tell that it was a lot smarter than i was, and was even responding to my questions seemingly with more information and more intelligence than i had at that moment. i almost felt like it was creating a narrative for my brain to follow, then when i didn't exactly follow that train of thought it would nudge/guide me towards thinking certain things. basically, i learned that my brain is a lot smarter than 'me', and that there was a 'me' separate from the impulse-control lizard brain.

That is what I call the higher self. It is basically the intermediary between your soul, and god.
