When you wake up in the middle of the night, only to discover that you never went home, and were sleeping in the closet of the test room.

When you wake up in the middle of the night, and find yourself with hands in Lathe handle positions.

When your dreams are of turning down aluminum

When you wake up in the middle of the night and yell "I've got it" and rush straight into a wall, believing to be at the robotics room still.

^all of these have happened to me^
