>>4 Thanks for your reply.
I see. It´s right what your roommate said, physically you can´t scream. When sleep paralysed you aren´t able to move, so you´re also unable to scream. Nevertheless you´re definitely screaming inside yourself, your voice is just unable to leave your throat. Means nobody is able to hear you calling, but you think you´re screaming your mind to the heavens.
By the way, does your body hurt? Do you feel something like prickling?
In my opinion you´re suffering from stress. Going to college is a one-eighty turn of life; all the new impressions, new places, new people, a lot of stuff to learn - when you´re psychical labile it could become too much pressure at once, causing loss of weight and sleep disturbances.
You should find a way to relax - may it be drawing pictures, playing instruments or doing yoga - something to equilibrate your inner balance. It could take some time, but it might help.
And don´t be afraid of getting sleep paralysed again. Being unable to breath is often only caused by panicking because of being unable to move.
One last question out of interest: When sleep paralysed, are you able to leave your body? Kind of like an out-of-body experience?
