I had a very similar experience, over 20 years ago. Son-of-a-gun, that's round about the same time, yes?
Deeply depressed, I began my search for enlightenment, and prayed for reassurance. For a long while I had been having trouble sleeping, but on this one night, right after I prayed for help, I fell asleep soundly, for hours. I woke remembering that I'd just been someplace extraordinary. Wherever I had been, I had no form, but there was brilliant light all around, pure energy, and a maelstrom of wisdom and knowledge flowing in and around me. I can't even remember a sense of self..just being part of something wonderful.
Yikes, I was in a panic..and wanted to go back immediately. I've not a clue as to how long I was 'there', although I am sure in this world I was only in that state for perhaps a few fleeting moments, or even seconds. I remember unbelievable peace and joy, and a sense of 'being home'.
I've spent hours, days, years, pursuing that state of being, trying to recapture that fleeting moment, and the hope of knowing that such states of being are possible has kept me going, all these years. If there is a better state of being than even that, then I'm all for it, too, but I credit that bit of bait for getting me going in the right direction.
So count yourself lucky if you've had such an experience.
