Ganzfeld Effect – In the process

I narrowed the selection from the thumbnails to 5 (6 if you count the one that I did twice, but differently). I wanted something graphic in nature. Eye-catching, but also a cover that would describe the Ganzfeld process a little, so the inside jacket could essentially make sense of the cover. Out of all of these I would have to say that I care for the bird eating the brain and the one with the man “throwing up” his thoughts.
