''Prove to me you're not dreaming now. You can't. No one can.''
Oh, for heavens sake, not solipsism again! If you can't tell the difference between your awake state, interacting with the external objective world where how you respond can be a matter of life and death, and dreams where you can fly or leap off cliffs and wake up uninjured, there is something wrong.
You want proof? Get a four pound hammer, place your fingers on an anvil and give them a good wack......that's reality.
