Why Do We Talk in Our Sleep? Expert Explains

Talking in one's sleep is categorized as a parasomnia, an abnormal sleep behavior that happens without the individual's awareness. Dr. Sood elaborated that this can occur across various sleep stages, with most people having no recollection of their nighttime utterances the following morning. Factors like stress, lack of sleep, illness, and disrupted sleep patterns can contribute to more frequent instances of sleep talking.

Explaining the mechanism, Dr. Sood noted that the brain remains partially active during sleep. Specific neural networks responsible for speech can momentarily engage, leading to coherent words and sentences even though the person doesn't fully wake up. This insight helps clarify when sleep talking is a typical occurrence and when it might warrant further consideration.
