Do you ever?

Do you ever get the feeling, when you're driving home, and it's late at night, and you know you're tired but you're pretty sure you're awake enough to be able to make it home - that maybe, you've actually fallen asleep on the road and that you're dreaming the fact that you're driving? Now that I think of it, there are two parts to that. First, the chance that you could be dreaming that you're driving. Second, the chance that while you're doing that dreaming, you're also actually driving.

No? You don't?

Oh, me neither.
