Yea you should be good. I'm still a teen and when I should be getting 8-10 hours per day, I actually get about 6 but I'm still able to have lucids. That being said, my chance of lucidity in a dream as well as my quality of dream recall is greatly improved with 8-10 hours, rather than my usual 6. My recall has been slipping recently, and for some reason in the past week I've only remembered 2 dreams, both of them lucid dreams, the rest seemed to fade too fast.
