Perhaps I exaggerated in my explanation, I do feel happiness, but not with the sort of "exploding with joy" feeling, and even when I strongly feel a positive emotion it is rare that I display it in the expected manner; people often say that I seem indifferent to things, but the reality of it is more that I have not developed a normal emotional mechanism for expressing it like others do. Though I am a bit indifferent to some things too of course.

I would agree that the idea of a chemical imbalance is a possibility, but there's more to my brain, as there always is with anything else...


Anyway, as for fear, yes, intense fear and the like used to be absolutely normal in nightmares (and waking life), but I don't really have nightmares anymore. In fact, see my latest dream journal entry for more context. That dream should easily have been a nightmare just for the first bug that appeared, let alone all the spiders that I saw after.
