Reoccurring dreams

I have only had two reoccurring dreams in my life.

Dream #1

I am walking in a backyard full of cracked cement and thick vines. In the corner is a broken fountain full of stagnant green water. I see something move inside and I go over to investigate. Suddenly I am in the fountain and a giant water snake is swimming around me. I swim away in slow motion and wake up right before I get bit.

Dream #2

I am in college and I wake up to discover that I have to take a final exam for a class I have never attended. It is too late to drop the class and I panic.

Interpretations anyone?
