Crazy backwards writing

[Autocratic]

So I was just sitting in one of my classes daydreaming when I realized I was a few lines behind on notes. I turned to the notes of the kid next to me, but it seemed to be total gibberish. Upon further inspection he was writing everything backwards. The letters were all in order, but each was backwards. Is this at all common? Is it a form of dyslexia? I've never witnessed something like it.

As a side note the kid was also crazy in other ways. He had three pens in his right hand and one in his left, all different colors, and was constantly switching between them for various different sections of his notes.
