You dont sleep well, flitting between dreams and nightmares... perhaps you woke up because you knew something was wrong.

... Or maybe you were just lucky.

You open your eyes to see Astarion, right above you, his mouth wide as he's moments away from biting into your neck. He froze the moment he saw you were awake, and he backed off, "shit- Nono, its not what it looks like, I swear! I just needed- well, blood-"

You then finally see him for what he truely is....

A vampire.
