Waking consciousness is perhaps one mode of consciousness we experience as reality, dreams are a different mode of consciousness we experience as a reality, say that's a lower grade of reality to the one we're experiencing now if it's non-lucid. Death would be a different grade of consciousness again we would experience as a reality, though this would be on a higher grade to the non-mystical waking conscious state. Certainly that does appear to be the case in people who report NDEs. There may well be a difficulty in translating memory from the different grades of consciousness as we know we can't easily recall dreams so that would make sense.
Come all ye faithful joyful and triumphant.
