I have plenty of experiences, falling from buildings, evening
"bouncing", like descend, reach ground, then ascend,
lol...sometimes upon reaching ground will wake up suddenly,
woo
Another kind is you sleep like for 5 mins, den suddenly ur whole
body twitches violently and suddenly, den u wake up den sleep
again, often happens to me when i sleep on sofa. My fren says he
WILL have it when he sleeps at night, if he had an afternoon
nap.
As for the "bei gui ya", my version is suddenly awake, den discover
that you cant move AT ALL, but my eyes can open but i don dare
haha, like ur body is paralysed like that. Scientific explanation:
You brain produces an amino acid (issit glutamine? forgot liao)
when you sleep to paralyse
ur body, yes to paralyse so that you wun act out your dreams! If
you suddenly awake, then the effect haven worn off, so u cant move,
after a while, u can.
