Interview speaks with actress and writer Kathleen Frazier, author of the new book Sleepingwalker: The Mysterious Makings and Recovery of a Somnambulist (out this week via Skyhorse).

SARAH HERRINGTON: What made you tell this highly personal story?

KATHLEEN FRAZIER: Necessity, really! I was coming off of the medicine that I’d been on for over five years, which had kept me still in my bed and—along with therapy—had abated the sleepwalking and sleep terrors. I wanted to conceive a baby and there was a heightened risk of birth defects associated with that medicine. I was basically willing to do anything to keep the sleepwalking at bay. My mentor, Ellen Burstyn, suggested that I write about my experiences. As I wrote, “the more I wrote, the better I slept.”
