The same thing has happened in a lot of my dreams. When I'm in a dream, sometimes while I'm walking or about to run I can't, it's like my legs give out on me. Like I just start losing all of the strength in my legs, and they slowly become sort of paralyzed. In a few of the dreams it turns into an embarrassing thing, like it happens in the middle of the hall in front of a bunch of people and I'm so embarrassed because I'm slowly crumpling to the ground. Other times I'm trying to run away from something, or run too something. Like I need to move but all of a sudden I can't.

It's happened quite often in my dreams. What does it mean?
