Brain crack

Yesterday I had a migraine.  I had trouble seeing, headache, nausea, and confusion.  I feel much better today.  This morning Holli informed me that she knew why I my head hurt yesterday.  She said that I was thinking too much yesterday and that my brain had cracked and the cracked brain was what was hurting and pushing against my eyes.  Ouch!  Guess I'd better cut out that thinking I've been doing!
