Liam merely nodded for him to go on. It wouldn’t be too surprising that the dreams themselves were causing issues. Most of the people on the network who were dealing with them seemed to be either repressing as hard as they could (not that Dr. Smith knew anything about that) or embracing the ‘meaning’ of the dreams wholeheartedly. But the situations in Ben’s dreams as described were incredibly stressful and likely to impact his waking hours.
Without knowing how though, Liam could only shoot in the dark. So he practiced patience, or silence, which often was the same thing.
