Every player is a hypnotist, or thinks they’re a hypnotist. A 1st player is selected to state something they believe.

Any other player can then claim they hypnotized that player to believe that statement, and why. Any other player can then claim why they hypnotized the previous player to believe they hypnotized the first one.

Play continues until the soft murmuring of hypnotists claiming earlier and earlier actions lulls all present into a pliant & suggestive state.
