Awww, that's alright! Try not to think about it too much, as that may only hinder you from what you want to happen. It happens to me all the time, especially since my school schedule is from 7 am to 6 pm, and by the time I get home I still have to do tons of homework and studying until midnight.

Lately my recall has been crappy as well, but from my experience, I learned to just be patient, because the less frustrated you are, the calmer your subconscious will be, and the greater chance for you to remember your dreams and even have lucids! Also, don't worry too much about dry spells, they WILL be broken and it will all be worth the wait! (Hopefully haha)

Anyway, you can do it!
