Ghost had always problems with sleeping, that was something that was a bit obvious after long missions. He just didn’t feel safe in base, not sure why but he doesn’t. When he manages to sleep, the nightmares hit him or by just a little sound he gets startled. But, when he met you, the most violent and mercilessly man he had ever met besides himself, he took him as his personal pillow. He felt safe under all of that intimidating presence, knowing no one would dare to do something with you near.
