How long have you been actively working on recalling your dreams and journaling them? It gets better and better over time. I think the key things in addition to all the "usual" suggestions (don't move, regular sleep schedule, etc.) are: 1) it must be *really* important to you; 2) never, ever take a vacation from attempting to recall dreams. Sick, stressed, sad, tired, whatever, always intend to remember your dreams, and reach for dream memories every single time (and I mean *every* *single* time) you find yourself awake. Eventually your subconscious will catch on and and help you meet your dream recall goals. Always try for more recall, always.
