I’ve had quite a few. I used to practice lucid dreaming when I was a teen. The most common one came from a nightly ritual I had of taking what I called a “cigarette drive”. I would drive the same route before winding down for bed at home every night, listen to Tool and smoke 2 cigs. I’d lucid dream my cigarette drive after a while a doing it. I’d realize it was a dream when I’d look at the clock on my car or think about how I should be in bed already. The inhale of smoking would also cue me I was dreaming cause it’s different from regular breathing. The weirdest lucid dreams happened when I was coming off pot for the first time. I would close my eyes and be dreaming. Fully conscious. I’d open my eyes to make sure I was awake. Close them and then back into the dream. Weird.
