Embrace it!!! It makes things go much more smoothly and it give you time to think about other things.
It's happened to me many times... I'll come out of a lead and ready to go into the third verse and, like a deer in the headlights, I'm completely clueless on where in the song I am, what the words are or even what the song is that I'm playing. You just have to let the muscle memory go on for a bit more until you recognize the song and the bass player tells you what the next line of the lyrics are.
