If you’ve ever talked in your sleep, you likely only know about it because someone else was awake to hear you. And when that person told you, a sudden, profound feeling of panic may have led you to wonder: Did I reveal my deepest secrets — just like in the 1983 “Talking in Your Sleep” song by The Romantics?
Probably not. Deirdre Barrett, a psychologist and long-time dream researcher at Harvard Medical School, says that sleep talkers might describe an intense, important thing from their lives once in a while, but it’s often mixed in with gibberish that makes it difficult to tell fantasy from reality.
