Write the name of the person you are wondering about on a piece of paper. Fold the paper in half, then half again. Draw an eyeball on the outside of the folded page. Slip the page under your pillow and before bed repeat as follows:
With dreamers eyes I seek to see
What this person thinks of me.
Be it good or be it ill
Reveal to me as is my will
Close your eyes and picture this person sitting across a crowded room. The room is all a buzz with conversation you cannot hear clearly. This is gossip about you that this person started. It may be good things and/or it may be bad. As you move towards the person let yourself fall asleep. When you wake, jot down what you heard in your dream, particularly anything s/he said or did. Your answer will reveal itself. If you do not get the answer to your questions, consider what was revealed to you instead. Perhaps there is a truth you are missing that is more compelling then the one you seek.
