I don't get fears of paralysis, but that's not a big fear for me. I have dreams that involve nasty insects, or being trapped in a plane that's crashing.
Strangely, I have dreams of owning a property, and it falling down around me I think we have nightmares about things that scare us.
My nightmares and my great dreams are very closely related. Water, lots of water, and being able to move in it the way I love is great, then it turning around, and me getting caught and drowning or suffocating is awful. There are great architectural dreams too, full of active exploring, they can end in getting completely lost and stuck.
Dreams packed with socialising, I hate those, I wake so exhausted after dreams like that.
