Your Tongue Can See

Mike Ciarciello has been blind since birth but says that in his dreams he can actually see.

"I have had dreams where I have been flying, you know, like in the air. I am not even bumping into any obstacles whatsoever. I am actually free, in my dreams," he said.

His dreams are closer to reality than you might imagine. He is about to participate in an experiment in which he will "see" by using his tongue.

At the University of Montreal, researcher Daniel Chabat prepared Ciarciello to walk for the first time through an obstacle course without his cane.
