Last night I had a dream that I was watching a trailer for a new Mario game. You hit the characters up in the air with golf clubs and they would get stuck on a magnetic semitransparent square above the field that allowed them to roll through the air and collect coins and other items before drifting back down. The trailer was following Mario, Luigi, and Bowser as they demonstrated the gameplay. But because the square was, well, a square, it had finite and very sudden edges. At one point, the camera followed Luigi as he rolled right to the edge of the square.
‘GOODBYE LUIGI!’ came up in the cheery Mario font, Luigi plunged from the sky with his usual wail, and the camera switched back to Mario and Bowser.
Luigi did not reappear for the rest of the game.
