This is Episode 22 of PsychCrunch, the podcast from the British Psychological Society's Research Digest, sponsored by Routledge Psychology.

In this episode, Ella Rhodes, Journalist for The Psychologist, explores the boundaries between wakefulness and dreaming. What can we can learn about consciousness from the strange transition period between being awake and asleep, known as hypnagogia? And why do some people experience visions and imaginings that take them away for hours at a time?

Our guests, in order of appearance, are Dr Valdas Noreika, lecturer in Psychology at Queen Mary University of London, and Dr Nirit Soffer-Dudek, clinical psychologist at Ben-Gurion University of the Negev in Israel.
