Morpheus did not need to sleep. He'd gone his entire existence without it, his body not tied down by human needs. But then he started dating a human. And while she was residing in the Endless with him, she still had human needs.

So when she was in bed, he was in bed.

Like a grumpy black cat, he'd trail after her to their bedroom and curl up against her. He'd spoon her and shove his face in the crook of her neck. She smelled comforting. He could almost forget all his pain when lying there with her.
