a somnophiliac (person with somnophilia) is a person who had a fetish for touching/caressing a person sexually when they are asleep or unconsious. This can also include sleep rape or oral sex which is understandable.

I think the main reason for this fetish is cause of the cute vunerablity of the sleeping person.
I myself am a somnophiliac. I have this odd overpowering fantasy involving me in a relationship with Anton Yelchin and i ... touch him amorously when hes sleeping.
