Why do humans sleep? How much do we need to function effectively? How are our sleep patterns affected by artificial light? What, if anything, is accomplished by dreams? Do they have important personal meaning and provide portents, or are they just random activity of a brain left to its own devices. Why are they so hard to remember? Can we control the course of our dreams? Where do nightmares come from? New insights are emerging into the meaning of sleep and dreams.

This is a part of Glenn Wilson's series of lectures as Visiting Professor of Psychology, 2012/13.
