If time dilation is possible in a lucid dream or psychedelic experience, and NDEs are a form of lucid dreaming or psychedelic experience, does that mean that when we die, we start to experience a lucid dream of infinite duration? It's an idea that I've seen people mention on other forums: that at the time of death, our sense of time gets stretched out to infinity, and even when the "outside" world goes on we're still inside that moment of death for eternity. Could that be what the afterlife is? A lucid dream that feels like eternity to us but is squeezed into a split-second?

I really don't know. But it's an awesome idea, and I'm interested in time dilation in lucid dreaming regardless. It'd be cool if I could enter my own personal Matrix and be there for days and days, and then come back and it's only been a few minutes or hours.
