What is the purpose of the astral realm? So quick summary of my situation, I'm basically in a period of isolation and I'm getting bored with the physical world and I hate everything about it. From work, to the system, and the mass confusion amongst everyone about everything. I've been suicidal since middle school and I've always had a thing for escapism. Weed, alchohol, music, fictional shows etc.

I'm creative and want to create my own fictional world. I had an anime I was writing but I lost inspiration.

Basically my question is, I want to use the astral realm as a form of escapism instead of thinking about suicidal thoughts.

What is the purpose of the astral realm? What can I learn there that I can't here given all the technology and information/books?

I never done Astral Projection before. I was close one time while attempting it and I fell my body kinda rise up and I just woke up out of it. I wasn't ready then lol.

How would I even begin to do it, or prepare myself for it?
