You're gonna hate me for saying it, but a dream journal is not necessary and can be restrictive. If you record your dreams, they will gain a pattern only because yoy believe you see a pattern. Well its useful for starting to LD, but then you lose the originality of the LD slowly the more you record and change to what is logical. Its more interesting to see how you are thinking and remember the dream in memory. Recording it, I believe could hurt the process that makes it random.

But oh well, what do I know. I just like to throw things out there.
