A guy joking about having his baby?

I've been dating this guy for about 3 months now and he always jokes around about me being pregnant with his baby. No, I'm not fat! I'm actually pretty thin & were both 23. & he's even told me he's had a dream about it. I know he doesn't even wanna settle down anytime soon, why would he always joke about that though? Or is he just trying to be funny?
