Hey congrats on the lucid! I had one like that once, where my bf's alarm went off at 5am, and I fell back to sleep. I was immediately dreaming about being in our backyard, in broad daylight. I thought "this can't be right, it was 5am like 4 seconds ago.." BOOM! lucid. That's good that you're questioning things.

Also cool that your clarity spell worked. In terms of remembering your goals, I imagine you'll get it pretty damn soon, since you're remembering to yell "Clarity" in the first place. My advice would be to pick 1 or 2 short goals to remember at first: like licking a random object, and looking at your dream clothes (<< love that second one!). Then make yourself remember just those 2 every night. You'll be surprised when they pop in your mind as soon as you get lucid the next time. I got good at that by making myself remember the TOTMs that I want to do. It's really fun and interesting to give yourself notes in waking life, then seeing how they carry over into your dreamworld. You become your own best friend in a way.
