@Bird mama that is a form of meditation! It's called trance dance. Gabrielle Roth has a series of videos called "The Wave" dedicated to trance dance. (See Youtube). I also have Shiva Rea's Trance Dance DVD and CD, and her other music CDs.
This is a great thread. I meditate regularly, either on my own as one poster mentioned, just sitting and listening to the sounds of nature, to Youtube videoso and soundtracks, sitting on the beach watching and listening to the waves.
For people who don't like to sit still, there is moving meditation. Lee Holden has wonderful Qigong videos that are user friendly, feel good, gentle meditative routines.
Here is one of my favorites from Youtube: The Forest
