it has been said you cannot die while dreaming in your bed "Not True", I say! my deaths I've seen in dreams along the way I've drowned, been shot and stabbed and crushed, but I find more often than not none of those things repeat like the dream, my body, from the rafters swings all dreams 'til now but one day soon I'll die and know not how
I meant that as you're dying, and you realize that you will die, how do you cope? Or do you? I've only had a couple dreams like that myself where it's vivid enough to come to complete peace with death... profound stuff! And of course, always nice to wake up after that.
I was once shot dead in a dream in a slow motion Matrix-esque sequence after shooting Matt Damon as Jason Bourne. The dream in its entirety was quite long and is one of the favourites that I've had. Of course as it's impossible to imagine pure nothingness everything was just empty darkness and I was repeating "I've got to wake up" over in my head until I woke up. I wasn't amazed to find myself alive but I was certainly shaken a little bit. It wasn't as scatty as when I had a false awakening. That was one of the weirdest things I've ever experience. Also the time I awoke from a nightmare having a panic attack wasn't particularly fun either.
I've experienced "false awakenings" a number of times. They usually happen after a dream that I have where I know that I am dreaming. For example, when I have a "lucid" dreams in which I am flying, I can control many aspects of the dream. Then I will cease having that control and be in a normal situation and feel as though I've woken up and I'm in reality. These dreams are often pretty scary because they seemingly have consequences. Most of my dreams on some level I know that I am dreaming but with the "false awakening" dreams, I don't at all. When something goes wrong in the dream, I really feel like it's happening. Waking up to a panic attack would suck. Sorry you had to go through that.
