Tonight I saw what seems to be a mandala pattern with a face in the center. It had the appearance of a 3 dimensional face protruding from a flat design. All in a darker shade of blue. The flat surface was much like a printed circuit board in a mandala pattern. At first I thought something had invaded my space, but when asking I wrote out 'Green Man'. Why the hell would Green Man appear to me as blue?

Pattern was similar to these, in the darker shade, with a face mounted in the center.
