Why do people twitch, or jump, while they are falling asleep?
Ah I hate these! It's a called a hypnagogic jerk and they occur during the transition between being awake and asleep. There are a couple of theories for them, such as accidental neuron misfiring, but I like the evolutionary approach to the phenomena.
The Short Answer
Ah I hate these! It's a called a hypnagogic jerk and they occur during the transition between being awake and asleep. There are a couple of theories for them, such as accidental neuron misfiring, but I like the evolutionary approach to the phenomena. The theory goes that the jerk originates from our origins – when we may have been resting up in trees and hiding from predators. Accidentally falling asleep in these conditions would definitely benefit from this sudden hypnagogic jerk so we could quickly grab a branch to stop us falling out.
