Tom Stafford, a renowned BBC contributor, says that the door to the world where we are asleep and the outside world did not close completely, therefore there are two types of involuntary movements of the sleeping brain: eye movements, as the eyes move in accordance with what we dream, and on the other hand there are myoclonic spasms.
Finally, the specialist says it seems to be a sign that the motor system can still exert control over the body , even when the muscle paralysis characteristic of sleep takes over. We don’t have a switch to wake up or sleep, he explains, but rather two opposing systems that have a pulse between them to exert control.
In short, the process of incorporating sleep, or rather the struggle between both systems, is what can cause us to jump in bed. Although it’s said that what happens at that moment isn’t so clear, it can be said that while we enter deep sleep and are already experiencing body paralysis, there is still daytime energy left , and this erupts in random movements; it is then that the sleep occurs in which we fall or stumble.
