Lucid dream about 12 years ago.

I was 18 and in rehab for the first time when I had my first lucid dream. I had been practicing a journalling activity that consisted of writing: "I will remember my dreams" like a punished school kid before my time in repeated lines. We weren't allowed to smoke cigarettes in this facility and fell asleep with a nicotine patch on. I realized I was dreaming somehow and tried to fly. But, I tried too hard and woke up trying to get out of bed. Thoughts?
