Please Tell Me I'm Not Alone

Occasionally -- last time was a few days ago -- I had the eerie feeling that my head was literally screwed onto my body incorrectly. It felt like it was skewed to the right. To fix the problem, I have to deliberately hold my head to the left -- and I can feel it as if I'm working rarely-used muscles -- for a while, until the sensation of leaning to the right ends.

It's akin to the classic Peanuts strip by Charles Schulz, in which Linus "becomes aware of his tongue," and is distressed that he can feel it pressing against his teeth. His paranoia spreads to his sister Lucy, who bawls him out for being foolish about the situation, then becomes "aware" herself.

Please tell me I'm not alone with this.
