Thoses drugs are dangerous and do not cure a patient usually leaving them in a worse state mentally. When you are the one forced to make these decisions its tough because there are no easy answers.
I find the traveling through time reference interesting. I remember the line from slaughter house 5. What cosmic truth was he approaching?
> People see distorted faces, visions, hear things and the worst part are not these hallucinations, but delusions, strong beliefs

> ome internal conflicts ... and then started decompensating
If anyone is interested in a taste of what that might be like, the recent game "Hellblade: Senua's Sacrifice" is very impressive. It's basically a psychosis simulator, developed under heavy consultation from a group of patients that suffer from psychosis/delusions.
Similar to how you mentioned it's not just the hallucinations, the game does things like using "find the perspective that makes those logs look like a rune/glyph" to prime/encourage the plater to see potential "deeper meanings". Headphones are required, because binaural recording techniques are used very heavily to e.g. place voices in specific locations "in" and around your head.
Warning: this recommendation includes a very strong trigger warning re: grief, mental and physical abuse, and (obviously) the very graphic realities of severe psychosis and other mental health issues.
