Error's POV:

I wave of pain hits me, causing me to curl up on myself and let out a whimper.

"Why don't you get some sleep?" Cross suggests.

"Actually... Dream and I kinda had to explain what sleep was to him last night..." Nightmare addressed. 

I didn't see how they reacted when another burst of pain came. I squeezed my eye sockets closed and let out a whimper. I felt someone adjust me so I was in their arms. I leaned onto them right away.

"Why don't you just rest Error?" I heard Dream whisper. I nodded and relaxed my body. As everything went blank, I felt someone pick me up.
