Blindsight

Blindsight – just how powerful is our subconscious mind, sensing things we have no idea of? Researchers find a number of blind people can subconsciously see, even when consciously they swear they see nothing at all. It opens the door to say we all have things we sense that we’re not aware of. The ability is already there. We’re just not aware of it … yet.
