Host Meg Wolitzer presents three works from an evening with author and New Yorker cartoonist Roz Chast, inspired by Chast’s new book I Must be Dreaming. “The Wife on Ambien,” by Ed Park, is a sort of late-night fever dream. It’s read by John Fugelsang. In Tessa Hadley’s “Bad Dreams,” images that begin in books envelop a family in real life. The reader is Rita Wolf. Tom Barbash’s “Stay Up With Me” charts the rocky path of an old love affair. It’s read by Jason Ralph. And throughout the episode, Chast describes her cartoons based on her own weird and hilarious dreams.
