What does it mean when I keep dreaming about an actress?

I know this is kinda embarring but why do I keep dreaming about this one hot actress? I'm not gonna say her name because then my question will get off topic. I'll only say that she's 23. Well anyways I had a dream that I made-out with this one actress and that she's always hugging me. What does this mean? And everytime I dream about her, why is there always an alligator chasing me around when she's in my dream??
