I think that lucid dreaming devices have been banned in the U.S., so I may have to get one elsewhere. I thought that I heard that there were law suits that they caused epileptic seizures, but I have know idea how epileptic seizures are related to lucid dreaming. Many years ago a friend of mine lent me her device for a trial and it seemed to work for me. Now I can't find any place locally that sells them, now that I'm interested in buying one.
