sometimes, i wake up, but do not have control of my body... it
is kind of irritating... i will grit my teeth hard, cause some
pain, and will suddenly gain control back. I will try to sleep
again, but sometimes, i will wake up without control... very
irritating thing to happen.
People who panic will usually find it hard to breathe for some
reasons.... just relax, try exert some force somewhere and you will
wake up eventually.
the science behind it is that the brain rotate between deep
sleep and normal sleep. sometimes when you wake up in deep sleep
due to minor disturbances, the switch back to being fully awake
screws up, leaving you awake with no control. can be cured by
outside stimulus or your will power to force yourself awake, which
happens in my case...
