Hypnic Jerk
Didn't you ever feel while sleeping that you are falling from a high place or falling?!
it could be that it felt like you were having a huge muscle spasm. You may have even felt a small shock sensation or a bouncing feeling.
During the most dream-filled phase of sleep, our muscles become paralyzed, preventing the body from acting out what's going on in the brain

actually,what you've experienced is called "Hypnic Jerk".It’s estimated that around 70% of people experience hypnic jerks at some point in their lives. I know I definitely have.
But what is hypnic Jerk exactly ??!
During this transitional state, the sleeping mechanism usually wins, but the wakeful one sometimes puts up a fight. “One of the things that happens as you fall asleep is your muscles relax, but the awake part may still be stimulating enough that it will temporarily overreact and you get this jerk of muscle activity,” he says. And for reasons that are unclear, it’s sometimes accompanied by an image.
Are hypnic jerks thing to worry about ?!
Hypnic jerks are nothing to worry about. If one wakes you up, simply roll over and go back to sleep. But keep in mind: a high caffeine intake, strenuous evening activities, emotional stress, or sleep deprivation may increase the frequency and intensity of hypnic jerks. If you suspect that one of these factors may be worsening your nighttime muscle twitches, try cutting back on caffeine, usingrelaxation techniques to help you decompress, or practicing better sleep hygiene. And if the jerks themselves
Some people report that hypnic jerks happen as they dream they are falling or tripping up. This is an example of the rare phenomenon known as dream incorporation, where something external, such as an alarm clock, is built into your dreams. When this does happen, it illustrates our mind's amazing capacity to generate plausible stories. In dreams, the planning and foresight areas of the brain are suppressed, allowing the mind to react creatively to wherever it wanders - much like a jazz improviser responds to fellow musicians to inspire what they play.
