Why do you sometimes get right until that time falling asleep?

Does it have anything to do beside your muscles? It's really unexplainable.Why do you sometimes get right until that time falling asleep?
It's called a hypnagogic myoclonic twitch or “Hypnic bump." It's extremely common, and happen to 70% of people right past they fall asleep.
The common consensus among researchers is that, as your muscles begin to slack and run into a restful state just as you are falling asleep; your brain senses these relaxation signals and misinterprets them, thinking you are falling down. The brain next sends signals to the muscles in your arms and legs surrounded by an attempt to jerk you put money on upright. This misinterpretation that take place in your brain may also be responsible for the “falling” dreams that shepherd the falling sensation. These “dreams” are not really normal dreams, as they are not produced from R.E.M sleep, but fairly more like a romanticize or hallucination contained by response to the body’s sensations.

It deal with the brain and keeping the muscles from moving. Our bodies are programmed or created really within a way so when we are dreaming, we don't achievement out what we're doing in our dreams. So that's what it probably is, bar that I can't really explain it.
