eli5 why do we talk in our sleep?
In: 7
During sleep, the brain kinda puts the body on standby mode. It stops a lot of the voluntary nerve signals from leaving your brain.
It can then use the brain to dream. Using the same parts of the brain during the dream as when you’re awake. ( Movement part of the brain to walk around in the dream, mouth part of brain to talk in your dream )
Sometimes this “standby mode” lets a signal through. This can come out as speaking, moving, or actually walking in some cases.
Standby mode not shutting down properly can also result in sleep paralysis.
