I do, however I have only written down one dream in it so far. I also have a physical dream journal with about 50 dreams in it, but haven't written anything in that for months. I should be more active.

You can write down some keywords with pen and paper if you want. Ideally you don't move and you don't open yours eyes yet when you try to recall your dream. You could also go through the dream in your head, then get up and type it in the computer.
