I read all Monroe books and Campbell's TOE. I also did lucid dreaming myself. I share the view that the universe is informational, but I think his experiences and conclusions are deeply subjective. Also, he does not drill down to the elemental, but builds on the idea that our world is the derivative of higher planes of existence/beings. Much like Federico Faggin and all religions. This answer does not satisfy me. I am more in favor of Wolfram's Physics, that builds informational universe from ground up using strictly math.
