I have an earthing mat I sleep on. It seems to reduce my back pain from having a less than optimal mattress. After sleeping without it for a couple of weeks I realized some low back pain I used to experience was coming back again. So I sleep on it regularly now. Something both my wife and myself notice when using the earthing mat is more vivid and memorable dreams. If you don't remember your dreams you will probably start experiencing that when earthing. Definitely worth a try.
