When Ray is confronting Debra about his annoyance with her sleeping so close, he is referencing Alien (1979). Specifically the process of the Face Hugger transforming into an Alien.
Ray says," I didn't want you to feel bad about ME not wanting to touch YOU.", to which Robert responded,"You don't want Debra to touch you?" What Ray actually should have said was," I didn't want you to feel bad about ME not want YOU to touch ME."
