I’m not sure if you’ve tripped before, but that hardly explains the reality-obliterating hallucinations on all sensory inputs. There’s feedback loops everywhere at that point. The moment there’s hallucinations or synesthesia you could argue the brain is not operating to spec and, at least temporarily, malfunctioning, as in, you probably wouldn’t usually be able to use your brain to overcome challenges it’s been designed to overcome when operating normally.

Hey I’m all for it, you can argue you learn a lot about reality itself once your senses go out the door and your brain stops processing reality the way we normally process it, but it’s still not how the brain has been designed to sense and respond to reality.
