Hehe. Yeah. I know.

Basically... just tell yourself something like, "Okay. Tonight, just this once, I will take a few minutes to write down my dreams. I'm going to be sleepy but it is only a one time thing. I'll be losing a little bit of sleep but it will only be for this one night." Then write down your dreams. I think if you really force yourself to do this and then see the results.. you very well may feel quite differently about this activity. You might wake up in the middle of the night and be excited rather than just groggy.

You don't even have to write a novel or anything. Just jot down key words or short phrases!

Otherwise, you could practice remembering your dreams after waking up from a full night's sleep. Maybe you won't remember much at first, but if you keep working on your journal, your recall should improve very quickly.
