Next time record your outer shell while doing this. You might discover that all of this is in your head.
All arguments made about god like things are true here too.
Things like: why would anyone care about us humans specifically.
Why would they be 'elves'.
Plenty of 'normal' people believe in very stupid things like loch Ness etc.

You could just do Aya in your lifing room tbh.
I personally would try to avoid assuming this is more than it is. This might become a dangerous brain and reality killing self journey instead of something crazy to experience.
For me personally LSD told me not that there is something else out there but allowed me to feel and realize how fragile my brain can be. It helps me to have more empathy for brain illnesses.
It also stabiled my life by knowing the normal boring world is just what it is: real. I still need to work and earn money and fees myself even after a trip etc.
