Ah yeah, I get that problem.

I tend to stop writing my dream journal when exams start, which tends to kill my recall until the holidays. I make a point of getting it back in the holidays. It's best to focus on recall during these times so you can carry it on through college. Also, I find if I don't have the time to write that recording my voice works just as well. I usually use my phone for things like that. Even saying them out loud helps.
