What could this be?

Usually dreams dont predict the future, its more of an indication of how you are feeling at the present moment, you might feel fearful or scared of a real life situation you currently have going on.

Like when i had that dream where my teeth all fell out, it feels absolutely real and awful, but the dream was just portraying my emotional state at the moment. So i tried to figure out what was bothering me and why i felt powerless in a certain situation i was in.
