I've had an exhausting weekend, and that reminded me of my oc Aria. She has frighteningly realistic nightmares that keep her awake and rarely ever gets any peaceful sleep because of that. The dreams disturb her enough that sometimes she even avoids sleeping if she can, kind of like a selective type of insomnia. But she'll crash eventually or her friends will force her to get some rest and she'll sleep for like an entire day or two.
