I jump or jerk in my sleep, if I have had a bad day, so although I think I am sleeping; my brain is still active.
Nightmares do this too.

While sleeping, your heart rate slows down. When it slows down too much your bodies self preservation mechanism gives your heart a jolt.
It is enough to make you flinch, but as you reach instant consciousness, it feels like you've leaped across the bed sometimes.

many times it relatively is by using the fact there is a few area of them "shocked" via the different area falling asleep. the main undemanding occasion is "nodding off" the place a seated individual falls asleep, yet their head slumps down and while it hits their neck or shoulder, they awaken, yet in easy terms sufficient to enhance their head, and the technique repeats some situations till now they get used to the thought their head is going to be in a humorous place for a on a similar time as.

A behaviourist psychologist would say it's because when we were apes and slept in trees it was a response to wake u up when u fell from the tree! That was Darwins evolutionary theory of this and i believe it!

The response comes from falling out of bed - we need to stay alert - it's a 'test' of our alertness.
