GfS: ....but your awareness, of things much larger and fuller, not subject to time fuses into your consciousness...and it's impossible, as far as I know, to discount it....as time goes on, there are reminders all along the way...that just keeps proving itself. Things fall into order...not an order that you can figure out, nor can you configure them out....but they make sense, as they unfold. That's one reason, people outside the experience can clamor all they want about a subject, that SEEMS to make sense to them...but it is only temporary, and in a short time is obsolete.
All I can say, respectfully, is it is like stepping into another dimension where your brain(for lack of a better analogy), sends and receives input far different than we do normally...and during one of these experiences, you have NO control, as to what is coming to you...hence the analogy of an orgasm is perfect!
Another thing to remember, is the experience is not just physical, nor mental...and is FAR greater than an orgasm. It is both 'great and terrible'!...

Seems to me that you have perfectly described the psychedelic experience provided by sacraments such as peyote.
