Sleep paralysis

Have anyone ever experienced that?
How do you manage to keep calm while it's happening?

I think that is when you're awake but still somehow dreaming? It sometimes happens to me, only 2-3 times so far. It's really scary. Too bad, I don't know how to keep calm.

I've experienced it, but I've only been able to remain calm when I've intended to do it, not when I've woken up into it.

Intended to do it? Who would choose to have it? Not me, that's for sure! I stay that way for what seems a very long time, and I'm trying to call out, but most of the time, no matter how hard I try, just a little noise comes out of my mouth. It can go on and on. Finally, I'm yelling so loud that my husband, who is watching TV in another room, hears me, and comes in and wakes me up. There is always a feeling that something or someone is in the room, and I can't wake up. So I try to yell out to scare them away, and get my husband to wake me up. I can't even count the number of times I've had them. Dozens, over the years. Sometimes they come in runs, and I'll have them 2 or 3 nights in a row. I'm also trying to move, and get out of the bed, but don't have the strength because of the paralysis. By the time I wake up, I'm all out of breath because of the tremendous effort I've made to wake up, my heart is racing, and my throat is sore. It's the pits.

It works as a great launchpad for lucid dreaming If you time an alarm clock to wake you up at the right point during your sleep cycle it can be relatively easy to remain in control once you start experiencing it, which then lets you slip straight into a dream while remaining conscious.

It would probably be possible to avoid it with the same method though. If you frequently have it, you could time an alarm to wake you up a bit before that stage of sleep hits. That way when you go back to sleep you should remain asleep through that deeper phase. It's when you wake up in that deep phase that sleep paralysis tends to occur, because it's an interruption.
