I fear the afterlife and not knowing what awaits me. Probably comes from watching “Event Horizon” in college and he says “hell is just a word, the reality is much worse”. Then I thought about eternity and I made me think too much.
There are only 3 possibilities after death.
1) Atheist belief: nothing exists but the material world. Just like going to sleep and fading to black.
2) Heaven & Hell: Those that believe this think they are going to Heaven and their enemies are going to Hell. Pure bliss with no pain or suffering.
3) Reincarnation: dropping one body and picking up another one. No different than changing your shirt.
None of the above three options is anything to fear.
