👉 Somatomonia is a medical term used to describe the involuntary muscle movements that occur during sleep. It's often referred to as "sleep paralysis" because it can happen when a person is asleep and their muscles are not functioning properly, causing them to move uncontrollably. This condition may be due to a variety of factors such as sleep apnea, sleep disorders, or even certain medications. Sleep paralysis can also occur during wakefulness but with no apparent reason for the movement.
