^^ That's not a bad idea -- as long as you're okay with losing the dream should it have been a NLD.

I sort of do the same thing myself, in that I usually write down my LD's when I get around to it -- which can be as much as a day or two later (they tend to be very long, so I have to set aside a good hour or more to record them) -- and am fully confident I'll retain them, but if I have a good NLD I grab my journal right when I wake up, because I know it'll be gone very soon.
