Yup... won't know either way for sure until it happens (could be today! Who knows), but at worst, if one just winks out like a light bulb, one will never notice. No point in fretting about it. One of the theories I like to roll around in my head sometimes is the idea that when one dies, one gets what one is expecting (harp and wings, virgins, demons w/pitchforks, another chance to overcome one's karma, etc.). Me, I want to be surprised.

I did have a dream once where (I think) I died, and found myself in this state I cannot describe accurately- a feeling of being nowhere and everywhere at once. It was startling at first, but quickly became very pleasant. Just as I was getting my bearings, ready to go explore, I woke up, feeling bitterly disappointed. Just a dream, but never had one like it before or since. A state of pure being, and pure bliss.
But I digress. Something that reminds me of reincarnation is deja vu. I used to get very strong moments of deja vu- one time, I had a dream where I was in a very specific place, and in that dream I was experiencing a feeling of deja vu. A few days later, I found the whole thing unfolding as per the dream, down to the last detail.... (cue "Twilight Zone" theme...). makes you wonder. But the whole thing may have been a trick of the mind.... time and space mean nothing in the dark corners of the subconscious.
