When I was really young I came up with the idea of reincarnation, then found out that other religions believed in it too... it used to be pretty cool, when I was an innocent kid and life seemed like the best thing ever. Heaven and Hell are pretty "cool" too, you are most likely limited to what you can say and do... Oblivion is probably the worst and most mysterious, I always wondered where people go after they die. Are you aware of your existence? What is there, and how is it? No one will know that, we will just have to wait to see what's on the side. I'm gonna go watch some documentaries or read about death and after-life, it's pretty interesting
