Dreamer’s Nightmare

You attempt to fill a creature’s mind with horrifying images of incomprehensible terrors. One creature that you can see within range must succeed on a Wisdom saving throw or become paralyzed with fear for the duration of the spell. The creature has disadvantage on its saving throw if it is nighttime. At the end of each of its turns, the target can make another Wisdom saving throw. On a success, the spell ends.
