That's something completely different. It's not something you've dreamed about that happens. It's when something is happening and you think its happened before, however it's purely in your imagination. I'm not sure what causes it, though. I think what you described is also a thing, coincidence, it's called.

Back on the topic of sleep paralysis, I've done some more googling, and it's also common to see or sense a ghostly figure in the room with you, and hearing footsteps around the house. I'm dreading going to sleep now in fear of having a worse episode. Main causes of it are lack of sleep, anxiety and stress. That explains a lot.
