In what do you record your dreams? Why? Do you find any particular benefits or limitations, particularly involving recall, with your medium?

I hand write my in a journal that I keep beside my bed and take with me on trips. I keep other things in the journal as well, which then enables me to compare my dreams with meditation work, life events, etc. going on at the same time. I like the ease of browsing through a notebook to find past dreams or to look up things like dream signs.
