has anyone else had an entire dream where suddonly at the end you wake up from a real sound to find that the whole dream was leading up to this one sound that you just heard?

i cant remember exactly what happened to me a few times but imagine this: your dreaming for what seems like hours. u are working at a factory trying to create and test a new type of whistle or an alarm. suddonly you hear the sound in real life and it wakes you up startling you, while at the same time you give first test to the new product in your dream. or your making preparations to launch into space and some outside noise finally sets it off but also wakes u up.


does this somehow prove time stretching in a dream has just happened? like did your mind just start to hear it and creat an entire 2 hour dream then you wake up in literally 1 second?


any thoughts
