So your consciousness was totally blacked out? Zero, zilch?<quoted text>
I did a very long reply to your comment, and posted it a few minutes ago, but it appears to have been lost. If it doesn't appear, know that at least I did try to respond. Because of the length of it, I do not want to have to retype the whole thing, other than I had no memory of anything while unconscious during either of my drowning experiences, which would have been perhaps 10 minutes tops, the first time, and perhaps 15 or 20, the second, but I was receiving oxygen during most of that time, because otherwise I would not be here typing today. Rescuers applied mouth to mouth resuscitation both times, as soon as they got to me, so I was told.
What about the realization you were drowning before such happened?
