I remember a couple years ago (highschool, yuck) I was walking down the hallway of my school and needed to go to a specific room. I thought for a second and then intuitively knew how to get there. I then tried to put it into words in my brain. I found that I couldn't. I was so surprised I stopped walking. I smiled, attributing it to my right brain wanting a monopoly on it. I'm very left brained.

At the time, I think I might have been taking some bullshit psychology class (that's what highschool is) and studying left and right hemispheres. Today I might split it into subconscious withholding it from me (the conscious). I was most of the way there when I finally got it into words.
