The only flaw I could see with this RC is that you may get so used to seeing the "A" on your hand that when you dream the "A" may carry over. This may not be true but usually dreams are about stuff that goes on around us and what we see every day. I'm not saying it's a bad idea because it's definatly worth it just to try this RC and see if there are any results. I'll try it and let you know what happens.
