Wow. Powerful experience.
I have no parallel, but I've read many Near Death Experiences and a few of those may hold insight.
Hellish out of body experiences are the source of the Hell myth. There is nothing permanent about it, but souls( for lack of a better name) can be stuck there until they release all negative emotions. We just can't evolve higher if we hang on to negative feelings. It may be a call for you to release your past (just a guess).
Peace :)
