You choose a creature within range. That creature must make a Wisdom saving throw or become convinced that it is being watched or followed by everyone around it. It is frightened of each creature it can sense for the duration and spends its turns trying to get out of sight. The creature can repeat the saving throw whenever another creature uses its action to shake the creature out of it, ending the effect on itself on a success. A creature that is immune to being frightened is immune to the effects of this spell.

A remove curse spell ends this effect.
