Nightmarish Sleep

The target must succeed on a Wisdom saving throw or fall asleep until the spell ends on a failed save the target takes 1d4 + your spellcasting ability modifier, psychic damage. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success and waking up frightened of you for 1 round. 

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, you can target one additional creature for each slot level above 1st. The creatures must be within 30 feet of each other when you target them.
