How can there be “colors which don’t exist here”? Do you believe that the spectrum of visible light increases after death? All this NDE stuff isn’t religion or theology, it is wishful thinking and superstition.
We can’t see most wavelengths of electromagnetic radiation, so if you could all of a sudden comprehend radiation in, for instance, the infrared or the ultraviolet, and experienced it differently than you had ever experienced any other color, I don’t know how else you’d describe it.
In this case, though, the person obviously isn’t experiencing anything in terms of radiation coming through their physical eyes. They are experiencing mental stimulii that are interpreted by the brain as visual stimuli.
So, assume that you have to describe in a biophysical sense what was happening when Joseph was told in a dream to take Mary as his wife or to go to Egypt…or you wanted to explain what was happening when you yourself had a dream. You do all sorts of stuff in your dreams that isn’t literally happening, but it isn’t either wishful thinking or superstition. It’s normal brain activity.
If we were telling someone who had no knowledge of visual stimuli of all the things that we experience as sight, of course we wouldn’t all be describing the same physical phenomenon from start to finish. We might all experience it the same, but that doesn’t mean it would all have had the same physical origin.
The interesting question is how many similarities there are in these experiences, particularly when they take place in someone who previously didn’t believe a word of it or who had never heard a word of it. Call it superstition, call it various experiences of the same unseen reality, but I think there is good reason to believe that our brain hardware usually comes pre-loaded with a lot of the same software.
