Lucid dream card

Lucid dream card, that's size of standard credit cards (visa, mastercard etc...). The purpose is to keep with you and periodically look at it and check if it's real right now or not, doing so lot of times will result doing it while in dream and thus become lucid. I had some success, this is not the only thing to do for lucidity but certainly helps.
The last line is "ERROR" reversed each letter, I remember I had some dream with error written but not quite correct way, it kind of reminds me of that dream, maybe will help you too to feel dreamy.
Height is 3mm, 2mm base and 1mm text. But I think better print thinner, instead 1mm base and 1mm text.
Printed with starry glow for base and bright green for top, fits well for the purpose.
