*"Come to your senses!" (4,3,2,2)
I think it could be either:
snap out of it
(Other definitions for snap out of it that I've seen before include "What one raiding photo album may take" , "suddenly give up" , "Shake off your bad mood!" , "cheer themselves up?" , "find photo frame empty?" .)
(Another definition for see reason that I've seen is " admit what makes sense".)
