Crop circles? "Crop didn't entirely shape there; vast middle part."
And this seems to refer to a friend who is very sick and is visiting the doctor a lot: "Sick; needs one trip herself fewer," with the last word of "fireplace" (which was in front of me in my living room).
The words are generated by the Ghost Radar at random; by what process, I have no idea.
However, I plan to leave it on when I go to bed, to see if anything interesting manifests.
