Why Do We Dream?

Now, when you lay your heads down to sleep at night, you might do so with the lingering hope that you’ll have sweet, and pleasant dreams. But so often dreams are bizarre and non-sensical,  but why do we do it? What is it that causes us to hallucinate while unconscious? Is it some sort of biological inheritance that serves no function or are we being trained by our minds to expect anomaly and change? Erik Hoel is a neuroscientist, neuro-philosopher and author of the novel ‘The Revelations’. He joined Jonathan to discuss Dreams and how they are more than simply images that accost us when we go to sleep. He argues that dreams serve a much more important purpose than they have previously been credited with, not so much random images and scenarios but something else entirely.
