Help me understand a visual odd happening? [View all]

Earlier this year, I had something happen three times that was odd.

1. Sitting at my desk in the kitchen, I saw, to my left on the white stove front, some red letters. Couldn't read words, but there seemed to be red letters (handwritten style) on the front of the range.

2 and 3. Days later, when I was in the recovery room from pacemaker surgery, I saw the same thing on the front of a large white cabinet near the toe of my bed. Red letters, handwritten in style, but not legible. Twice.

What the hell was that?

Any clues?
