I'm pretty convinced it's sleep paralysis. It's so amuzing
reading so many posts about it and how some brave ones overcame it.
There are so many people, including myself, who suffered or are
suffering from it.
Decades ago, when I was about 16, I too got very scared when I
first experienced it and thought it was some ghost or spirits
holding me down. After many many scary episodes, I started to
wonder why it happened only some of the times. I started to take
note of the time, the day, the month, sleeping posture, etc.
Finally, I noticed that the paralysis only happened whenever my
arms were stretched out above my head. IT WAS THAT SIMPLE. From
then onwards, even till today, whenever I begin to have this
paralysis feeling, I just re-position my arms to my waist and the
paralysis would subside immediately.
I cannot conclude that this remedy applies to everyone. You have to
observe what posture works best. I don't even want to conclude that
sleep paralysis is due to sleeping posture. It may be due to stress
or emotions. Be brave and find a solution.
Excellent explaination of a rather common phenomena
