Yeah, a topic which me as well has plagued a good time in my life, I'd say ever since I got deep with drugs / dissociatives / psychedelics. On mushrooms I saw ancient runes I never seen/known before, and this is just the most easy to describe experience. I'm not sure but might have been very close to death when overdosing dissociative+morphine, but unfortunately I didn't remember much from these experiences. Once I saw my life as a movie, in the literal sense, like a cinema presentation and came back with heavy euphoria (might have been influenced by that I was seeing movies before this experience/NDE? happend). Other experiences were more scary and there's a part of me which indeed is scared by e.g. biblical heaven and hell stuff. my conscious self doesn't really believe in eternal doom or heaven because what we do in our live isn't significant enough imo, it makes no sense that little sins on earth should bound us to hell forever..
But it also is important about suicide. Will a suicide be different from regular death through age, sickness or foreign influence? Would I become a ghost forever haunting through the physical world not being able to really influence anything? This comes close to hell I think. Or do we get reincarnated anyways? I don't know but I wanna know badly. At least we get born with complete amnesia which I question why..
Overall I'd say I believe in souls (they'd explain why we all watch from our own perspective, who's the 'me' who sees through my eyes, you know?) and that animals are/have souls as well but there it becomes tricky - has a bug or snail a soul? Are these young souls? Do you become a bug as penalty for sins or suicide? Some animals like cockroaches are simple enough to be simulated in computers if I remember correctly.
Or do we enter another universe? That thought came to me on DXM. I believe that there are no aliens in our universe, because it's just one of endless parallel universes and every species has its own universe maybe. When there are infinite universes that becomes a real possibility. Infinite is a damn big number. So this is possible as well.
Would say, I'd love to experience a ghost and NDEs too but yeah then indeed the question whether one should better not mess with these things, if ghosts are real then some of the warnings might have sense too. Some time I believed that a spirit entered my consciousness when I had psychosis. It told me stuff like that it was attracted by my 'light' and that it had no memories before that, and I now had to accept another entity - not real hearing voices but another train of thought. It faded with time and I'm not sure what the fuck this was. Maybe just a dysfunction of the brain, like a second mental 'process' which projected my fears ...
Very interesting question, will follow this thread!
