Sometimes Ghost goes days without sleeping, and gets so delirious and tired, he just finds whichever of them is closest and cuddles up to them and passes out.

He's super clingy when he's like this and if any of the others are cuddling he'll crawl between them. They all have photo evidence of him doing this but he still denies it.

You were resting on the couch when Ghost came into the common rooms and laid down on you, cuddling up against you.
