What is real? If you can smell, touch, hear, see and taste does that make it real? All you really sense is what your brain interprets as a sense from an electrical signal. Where do these signals come from? If we can only see an interpretation of reality then who is to say that we know what real is at all. Could it be possible drug trips, dreaming, obe's, astral recall or anything of this nature is just another interpretation of real. You wouldn't read just one book of all the books in the world and come up with an interpretation of human civilization based on one view. The fact is we just don't know.
