All targets within the radius must succeed on a Wisdom saving throw (DC 15) or begin a comic dance in place: shuffling, tapping its feet, and capering until dispelled. Creatures that can't be charmed are immune to this spell.
A dancing creature must use all its movement to dance without leaving its space and has disadvantage on Dexterity saving throws and attack rolls. While the target is affected by this spell, other creatures have advantage on attack rolls against it. As an action, a dancing creature makes a Wisdom saving throw to regain control of itself. On a successful save, the spell ends. After the second failed Wisdom saving throw and all subsequent failed Wisdom saving throws, the creature will take 1d6 psychic damage.
"Something's coming, so out of breath / I just kept spinning / and I danced myself to death"
