the subconsious mind or collective consiousness sees " i am not" the same as " i am" so it would not work . this is just my opinion but i have tried spread like this and it was most inaccurate.
HangedMan, this is a really great spread. It's a lot different than others, and when it comes to trying new spreads, i say, the more different the better.
I was wondering what the source for it is though? Did you read about this somewhere, or did you create it?
