A weird train-filled dream

Yesterday I dreamed of being a train driver where there was a system called "Automatic Signalling System" which replaced all the stop lights. There was also a button to acknowledge the warnings and alerts given by the system, just like the Automatic Warning System in the UK that was just labeled the "ass button" and a button labeled the "mutton button" which I was told not to press, ever. Then I pressed it and then woke up.

What would have happened if i woke up later? I don't know.

May the idiot be with you
