I would also add that the fear responses, while participating in the hallucinations, aren’t themselves hallucinated, not any more than wakeful fear is hallucinated, at any rate. They’re just emotional responses to the contents of our dreams.
I disagree with this statement. For me, the contents of a dream seem only weakly correlated with whether I feel afraid during the dream. I’ve had many dreams with seemingly ordinary content (relative to the baseline of general dream weirdness) that were nevertheless extremely terrifying, and many dreams with relatively weird and disturbing content that were not frightening at all.
