Insist that you were awake the entire time. You don’t remember falling asleep, so these people telling you that you fell asleep must be playing a trick on you. You’ve got to let them know that you’re on to them. Maybe you’re in a different location now: a bed instead of a moving car, a car instead of a friend’s living room, a different city entirely than you knew. Maybe you’re in the location you were, but now it’s dark outside, the daylight is gone. What kind of evidence is that, when all you recall is being awake, and you’re clearly awake now as well. Let them all know. Never falter. You were awake the entire time.
