I experienced sleep paralysis 3 times in one night last year for the first time. I was scared for my life, I seriously thought I was having some kind of stroke or seizure.
I went to work the very next morning pretty shook up, until my coworkers asked what was wrong and I told them about it. To my surprise, they've all experienced it at one point in their lives and a couple of them they go through it quite often.
I was relieved to hear that it was nothing serious and after doing research to confirm, I got some mental peace. I thought something was seriously wrong with me and that I would die.
