Pretty much. In ETWOLD it talks about waking up. One good way is to 'go to sleep', lay down and close your eyes, like you are trying to sleep in the dream. You will probably wake up in real life, but there are aloso those pesky FAs. And it said you wake up if you shout your name but I haven't tried it...
But one thin you gotts know is that you will wake up anyway when you REM cycle ends, or in the morning.
