HAVE YOU EVER JUMPED WHILE YOU SLEPT? HERE IS THE REASON FOR THIS PHENOMENON …

Did you ever wake up startled, thinking that you fell? This happens to almost everyone. Usually, this sensation comes to us while we sleep, or at the beginning of sleep.
This phenomenon is known as hypnagogic jerk, which is nothing more than an involuntary muscle spasm, which occurs when a person is drifting into sleep.

This pull is named after the transitional hypnotic period between wakefulness and sleep. Muscle spasms may occur spontaneously, or they may be induced by external stimuli, such as sound or light. Some people have suffered these “fall breaks” accompanied by hallucinations, bright lights or loud noises caused by their own conscience.
These sleep starts are quite frequent, about 70% of people experience them.
A hypothesis about why these hypnagogic jerks occur is that everything is due to a natural response of the body to the adaptation to alertness during sleep, which means that the nerves have a “ignition fault” during the process .

Another theory explains that the brain misinterprets relaxation as a sign of falling, so it induces the muscles to react quickly.
