I don't generally believe in woo things, but I had a dream once -
In the dream, I was in a hospital bed, and I knew I was dying. My sister was there with me, and she asked me if I was afraid, and I said no, to comfort her, but really I was terrified. I'm one of the people who is really worried about and afraid of death.
Anyway, in the dream, just before I die, I have this enormous feeling of relief - that it's over now, that I can look back on my life without a single regret, the good and the bad, because that was it, it's complete and beautiful in its own way. Then I die, and I feel my consciousness - dissipating outwards, and fading, but there's no fear at all, just this immense feeling of peace.
When I woke up, I was honestly surprised that I was alive and it took me a few moments to realise what was happening. But it's the most spiritual experience I've ever had, especially as I believe that dreams are symbolically powerful anyway.
