hmm, interesting, I will have to do a little research into it before I fully accept the idea but interesting none the less. I do still believe it possible for a blind man to dream sight but I won't claim it to be fact.

When I say I saw infrared it is hard to put into words that would make sense. I could compare it to something that is tangible to everyone else like saying it looked like such and such but then in saying that it looked like that I just gave you the wrong mental image. You would now perceive my seeing in infrared as merely seeing those colors. So, considering I have no ability to see infrared in real life I can still see what my mind has given infrared in my dreams. The way it interprets infrared electrical signals even though they are not visible to the human eyes receptors

The flight comment was that of human flight not machine induced flight. I have never and will never to my knowledge be able to fly in real life without external forces acting on me. But I guess you could say that my mind just creates the sensations that it thinks flying would give. so i will just put that argument aside.

Although I know not everything is possible in dreams I do believe that we have some untapped potential within our minds that is not being used because of the frailty and imperfections in our human physical form. In dreams we excercise more control over reality but I believe we also can access some of those untapped portions of our mind.
