a therapist once asked me to try this. she took a crystal object and put it on a piece of clear fishing wire and tied it hanging from the window curtain rod. I admit it was interesting watching the colors from the sun going through the crystal onto the wall. Quite hynotic and relaxing which is what she told me it was supposed to do. She said EMDR is supposed to work by relaxing the cleint enough so that they are not afraid to remember and talk about what happened to them. By bringing the situation back into the present and giving the client new coping tools the situation no longer bothers, upsets and triggers them. Basically this does the same thing that self hypnosis/hypnosis does and it does work but the client has to have complete trust in their therapist so that they are willing to be open to looking at what happened. As for how it worked on me - It was relaxing but that was as far as I was willing to take it at the time.
