I Suffer From Sleep Paralysis

It happens when i lie on my back and sleep at iregular times mostly. But it reeeally sucks and its super scary not being able to call for help, you just lie there and fight to get up and if you do nothing it gets heavier. Like something is sitting on you- when I was younger I used to think it was spirits holding me down and my mom didn't help either (she said it was cause of the worldly music). It wasnt until I looked it up and consulted a professional that I actually realised its a condition. Just something I live with now.
