In this episode, we talk to Professor Tore Nielsen from the University of Montreal and Professor Mark Blagrove from Swansea University.

In part 2 of this two part episode, we carry on our discussion about nightmares and talk about Tore's work on imagery rehearsal. A process where the dreamer rehearses their nightmares finding solutions to them in waking life in order to reduce stress and anxiety around nightmares and find more control in their dream life.

Then we move on to lucid dreaming and how this differs from imagery rehearsal. We take a look at Mark's work on how lucid dreamers have more control in their waking life and go on to discuss the possibly positive and negative effects lucid dreams may have on our REM dreams.

Finally, we discuss work from both guests on the dream-lag effect. This phenomenon, first discovered by Tore, occurs when life events are incorporated into dreams the night after the event and also 5-7 days after, but not in between. We discuss how the dream-lag effect was discovered and how it only appears to happen in REM dreams. We also discuss what this may means biologically and what impact it may have on memory consolidation.

We hope you enjoy this episode!
