Where the researchers indicated that this phenomenon is considered automatic during sleep, as the person talks, walks and even eats during sleep. This phenomenon occurs in the stage of deep sleep and there is complete or partial forgetfulness of it after waking up from sleep.

The researchers reported that people who suffer from this problem have inflammation in a specific area of ​​​​the nerve cells in which the production of dopamine, which interferes with sending messages to the body.

The researchers explained that, in contrast, people with both Parkinson’s disease suffer from a lack of dopamine production because the neurons responsible for its production have died.
