Mind tricks

Have you ever noticed, as you drift off to sleep, that thoughts will surface of such clarity...thoughts that you wonder why you'd never considered this before? Something so perfect and clear. Only to find the next morning that the thought has completely evaporated, like fog in the daylight. Last night as I floated into the darkness, I had such a thought...a solution to an emotional quandary that had been bothering me during the day. I have spent a good deal of energy trying to recall that thought but it is nowhere to be found. Ahhhh the frustration.
