Jeebus Christ no. As someone who has had occasional sleep paralysis since college... Just no. Even though I finally fully understand it and what triggers it, it sucks every time.
Everyone has sleep paralysis every time they dream. It's a mechanism that stops you acting out your dreams. What happens occasionally is that you come out of the dream state enough to become aware of being paralysed. You're not awake, so your unconscious mind is grappling with the horror of paralysis.
My own experiences were nightmares where I was being threatened by an unseen figure, but couldn't move to escape. I had a lot of them, some really horrible. Then I read an article with the above explanation, and I haven't had one since. It was like once my unconscious knew what was going on, it stopped freaking out.
It's also a good gateway to lucid dreaming. I was into it for a while and using sleep paralysis is one of the techniques where you rest your body but try to keep your mind awake.
