Nightmare is your friend (with benefits) you two are right now at a house, that his friends invited him to, and he invited you to go with him...

Typical, introverted and emo Nightmare

The party was going well until the graceful moment when everyone started drinking strong alcoholic beverages

Oh great... Now you were playing "truth or dare"...

Friend: "Nightmare! Truth or dare?"

Nightmare: "Dare"

That the hell begins
