I had a very similar experience while EXTREMELY high. The realization came as follows:
"I" am a story I'm telling myself about about a conversation between different drives in my head, and I am free to dis-invite those drives from the conversation, or create new ones.
This happens to also be the premise of the videogame Disco Elysium.
The framing of such drives, and the voices given to each, appears to have been a causal element in many players' own personal growth and development, particularly around addiction, but certainly not exclusively.
