I flatlined after heart surgery in 2012. I went to a place that seemed really heavenly and was having a grand time. In what I can best describe as my "consciousness," my mother (who died in 1995) told me "You're not going to be here very long." I go back through a tunnel of darkness and I wake up to "360, no detectable pulse." But they brought me back. Odd thing is, I apparently have my mental faculties, but I'm more or less happy all the time. I just "know that I know" I'm going back to that place.
I am really sorry to hear that but that must have been a profound experience that must have changed you in some way or the other!
