Should you wake a sleep walker? Why do we sleep walk? And, how do we stop it happening? In this episode we explore the topic with Professor Matthew Walker (professor of neurology at the Institute of Neurology, University College London).

Plus we're joined by Dream Psychologist Ian Wallace. Professor Wallace tells us what might be happening in your subconscious to make you have the dreams you do. If you want to send your dream into the show for translation, email MeTIme@bbc.co.uk.
