Not to trivialize your experience, but Deloused the the Comatorium by The Mars Volta is a true story about a guy that tried to kill himself by drinking rat poison, going into a coma, coming out of it, and realizing that the coma world was more preferable/he couldn’t cope with the waking world and jumps off of a building to get back. He died.
It’s an interesting album that might help? There’s a lot of disconnected, out there nonsense in his dreams that they express in the songs.
I’m sure it’s not nearly as intense as being in a dreaming coma, but I found music that touches upon a traumatic situation helps me sort it out.
