Well, Brian Stark couldn't be blamed for thinking his first two dreams were a dream, because each of those dreams had taken place in places he had never seen before, unlike the last one which had happened in Amy's room.
Now, Brian Stark was certain that the man in his dreams and the one Mary described were one and the same. But he didn't understand what he did wrong to the man for him to target Amy.
'I'm certain he must be manipulating her to get close to me,' He thought to himself.
'But why?' He thought in confusion.
'Could he be the one responsible for the destruction of all four of my shipments?'
'Then, doesn't that mean he is the runt they call Boogeyman?'
While thinking about this with a bit of skepticism since he had no proof, Brian Stark turned towards Mary.
"You said you met them, right? Then how did you escape from the den of tigers?"
