I have a theory. what if our lives are just dreams. we might still be little babies in poopy diapers in our cribs sleeping right now, dreaming our futures and when we die in the dream is when we wake up, and when we went to sleep. or we could be in a coma right now dreaming of our past. that's why we cant really process what happened when we were really young, because that was the beginning of the dream, and this moment is the present tense of the dream/"real life". and like I said when we wake up from sleep or coma, if you do wake from the coma, then that's when you die. but the question is, how long have we sleeping. we could be old people dyeing in bed right now or dyeing in some way and have that "flash of life". we(humans)could just be the imaginations of a highly intelligent creature thinking of a new race/life form and we just don't exist.
