There are occasions when one notices the motion of an object before one sees the thing itself. Instantly, the mind does a little colouring in, drawing on expectations, or probabilities. Whatever fits best. Something in the grass by a pond looks just like a frog, then resolves into a leaf stirred by the wind. In abstract, this was one of those moments. A thought darted past me, or through me, then it was gone, and I couldn’t trust what I thought I had seen.
