That's exactly what I was getting at John11. Yeah you could just write something on your hand, but it wouldn't be anymore drawn in by your subconscious than the crazy shirt you might have been wearing for the last three days straight. It wouldn't be that important to you. But the tattoo actually becomes a part of your body. Therefore, it must manifest itself into the dream world noticeably enough to become an automatic RC. For me personally, I use just my hands without anything written on them to RC and I do know that during my regular hours of dreaming, I tend not to think of even doing an RC with my hand. Now if I saw this tattoo in conjunction with dream absurdities, I believe I would make the connection 9 times out of 10. I doubt I would ever get a tattoo anyway but the hypothetical really intrigues me.
