Dial that says 'low' at one end and 'high' at the other end

From Create Your Own Story

You turn the dial to high. You start to feel like you are flying. Then you realize...

You're high.

Soon unicorns surround you and then one gets ticked and impales you. You snap out of it... and realize that Willy Wonka just speared you with his cane. I mean the walking-stick kind, you perv. "Enjoy your experience? Too bad."

You die.
