Welcome! That was a good read and I'm glad your girlfriend broke through. As a long time rationalist and atheist myself with christian upbringing (though I doubt my upbringing was nearly as Christian as yours) I have a lot of trouble believing in anything like an afterlife or something like that, but if anything makes me want to believe in something more, it's DMT. The fact that such an amazing and powerful chemical exists on earth, and is made naturally, is almost unbelievable. It's like pure awe packed into a crystal. But it's even more encouraging to think about it as a natural chemical than something put here by a god-figure or what have you. Because the universe is amazing and DMT is just a testament to the power of infinite chance. And that's just the universe we know about, imagine what else is out there that we can't see or sense? Heck, we haven't even left our solar system yet.
