Slumber Confusion

How many times has this happened you today?

You settle down and you feel really relaxed. Slightly tired maybe. You close your eyes. You drift off into a deep and satisfying sleep. Dreaming perhaps. Perhaps not.

And when you open your eyes at the end of this slumber, you sit up, thinking you're in your bed and its morning. A second later and your brain has engaged itself. Its not the morning, its 6.15pm. And you are on the couch after a 15min snooze, not in your bed after a 6 hour sleep.

To answer the question I posed of you earlier, it happened to me once today.
