Although I have dealt with paranormal activities in my life, I am more and more inclined to believe that Heaven and Hell in the conventional way are not real. I have entertained the thought that perhaps everyone chooses their own afterlife, to explain how I could have had those past experiences, but this implies that humans have influence over what happens to them after death, which would either make humans more godlike than we think, or it would suggest that there is a god to grant our wishes. Standard Heaven and Hell wouldn't work, because forever being in "Heaven" to be with my dead relatives and seeing the world fall further and further into despair sounds like Hell to me, so then I could never truly have a heavenly experience, no matter how good of a person I might be. But if the afterlife is different to everyone, then that implies that there is some higher power. Although not impossible, it seems like a pretty far-fetched theory to go off of, so here's what I think in the end.
After you die, your brain dies, as do "you", and then your body slowly gets eaten by worms and bacteria. Food for the soil. The transfer of energy. Then, there is nothing. Not even nothingness in the way you can imagine, because if you're dead, you can no longer think and imagine. You will just cease to be.
The paranormal experiences I've had must have just been big coincidences, fueled further by childlike acceptance of the unlikely, and the people with near-death experiences who claimed to have "seen the light" were probably hallucinating because of their physical/mental decay. That's the only way I can sort of wrap my head around it. Heaven isn't real and "Hell is other people".
