Is it possible we receive some form of communication while dreaming from an intelligence on another M-brane?

Question

This is actually a legitimate question. Many modern day physicists believe we exist in a "brane" i.e., a layer of reality with somewhere between 4 and 11 dimensions - see "The Elegant Universe" by Brian Greene. Yet we would exist on just one of an infinity of branes. Supposedly the only exchange between the branes could be gravity waves. Human dream states are almost metaphysical in character. Could human experience while in such a state be influenced by other branes?

Answer 1

The catch here is that as far as we know, we have no way to detect the additional dimensions (at least not with current technology, and no ones can even speculate what technology might be needed). We're stuck with just four--3 of space and one of time. Even Brian Greene admits that many scientists quite legitimately question calling string theory a "scientific theory" because it cannot be tested (the gold standard for science).

It would not be a scientifically proper answer to say that it is impossible that our BRAINS (in our heads) can pick up some kind of information from another BRANE, but we really have to consider this to be very very very unlikely. Even if the branes can exchange information via gravity waves, we have absolutely no reason to believe or even suspect that the human brain is sensitive to gravity waves.

Answer 2

I never heard of branes, but it sounds like a book worth reading. Personally I'm convinced that people who have passed on to the next life (whatever that is- would it be another brane?) sometimes communicate with us through dreams. However the majority of dreams are just dreams, the result of an undercooked potato or whatever.

Answer 3

The effect of last night's dinner/ drinks/ indigestion on our dreams is far more significant than even the effect of our own gravity, let alone the tiny changes leaking in from a nearby universe.
