Blinding Nightmares

One creature of your choice within range becomes overwhelmed with hallucinations, causing it to be blinded and stunned until the end of its next turn. In addition, if the target fails an Intelligence saving throw, the target is plagued with nightmares every night. The nightmares prevent the subject from healing during a long rest. These nightmares can only be removed with a remove curse spell or similar magic.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, you can target one additional creature for each slot level above 4th.
