why does the body do a quick “jerk” or give the brain the feeling of falling for a second while trying to sleep?
In: Other
As far as I’ve seen, it’s a weird holdover from our evolutionary ancestors that slept in trees. It stands to reason that it would be beneficial to become alert if you have a sensation of falling while about to sleep. Although I really can’t explain why we get the sensation while perfectly stationary on a bed, but I’m not sure that has been explained by anyone.
