Also i know what cause it..
at least ON MY case...

it is 100% related to sleep hours..
or oversleep...if i oversleep
i can cause 3 or 4 sleep paralysis
in a day..

i m able to sleep as much as i want
for some reason but i do pay the
sleep paralysis price..specially if i join it with radically change sleep hours..

lets say i dont sleep from 00:00
and i go to take a nap from 14:00 foward
i m goin to take up..soon as 15:00
i can repeat as much as i want
but i wont be able to sleep more than 1 hour.. and for every time i do i will pay with sleep paralysis
