Sometimes I remember my dream later that morning. Like when I'm getting out of the shower or getting ready for school.
Just try to remember what you were first thinking and think about that when you're getting ready in the morning and it'll just hit you.

Also, try not to turn on all the lights on when you first wake up. It'll startle you and you'll forget the dream. I only turn on a shaded lamp on my nightstand and get up slowly. If I get up too fast, I can't recall any dreams.

The main thing is just to be patient and don't get frusterated or discouraged.
Good luck.
