Does not exist? LOL. From where do you think your "friends" came?
Sorry, but hell is as real as heaven, I visited different hells and heavens while doing astral projection.
Sounds like a fun trip in the astral realm @Arath but hell still isn't real.
But like I suggested earlier, reincarnation is certainly real but how that process plays itself seems to vary a bit sometimes based on culture, belief systems, upbringing, and how you died (violently, unexpectedly, old age, or just your time).
If you die unexpectedly or violently you seem to reincarnate much faster according to the research done. If you lived a full life in 3D human form, reincarnation can take longer but not always. Culture and belief systems seems to play a role in how fast reincarnation takes place.
But Hell as described by the bible/religion/church is not real and I know I'm much more content knowing that information now that I'm older. I wish I knew it when I was younger when I was being forced to hear about it in church & the bible as a youngin.
But to each his/her own @Arath - Maybe you just had a visit with some nasty entities that resembled a hell like vision? Just my guess, thanks for the response either way. I'd like to hear about your travels.
