first lucid dream

Brief and momentary, real: I became aware of my waist length hair and wondered what was going on, as my hair has been short for forty years.  It then dawned on me - "I'm dreaming!" I exclaimed to myself. I was joyful. That's all I remember. I occasionally dream I have long hair, usually flipping it back - this must be my wakeup object, rather than Castenada's hands trick.
