Dr. Matt Walker: The Science of Dreams, Nightmares & Lucid Dreaming | Huberman Lab Guest Series
About this video
In this final episode of Huberman’s six-episode sleep guest series, Huberman hosts Dr. Matt Walker to discuss dreams, nightmares, and lucid dreaming. Dr. Walker explains what happens in the brain during mundane and emotionally laden dreams, how to think about and perhaps interpret dream content, and what lucid dreaming is, a dream in which the sleeper is aware they are dreaming. They discuss nightmares, why they occur, and how to think about and address them. In the slices, Dr. Walker describes rehearsing an alternate ending to a nightmare scenario while awake, reactivating the trauma memory and replacing its horrific section with a neutral or positive ending, then consolidating that edited version during sleep over repeated nights. He reports this imagery rehearsal approach benefits about two out of every three people on average in the data he cites, and discusses a recent Geneva study building on it. The episode closes with rapid audience questions on sleep directed to Dr. Walker.
