He caught glimpses of them and they made his anger flare. How dare someone do this to people? How dare they violate their usually safe dream-state and use it to hurt them. He pushed his anger back down and decided to tweak the nightmare memories just a bit, just to lessen the impact of the blood and screams. It wouldn't do much but it was ease her mind at least a little bit.
With that done, he returned to strengthen her shields against the onslaught of outside influence.
