.... "a mood?" Not a good mood nor a bad mood-- just a mood that could go either way depending on your interaction with others. In other words, the demeanor you display would depend on the behavior of others: "A Mood"
I've also been in one of those weird moods (maybe due to my mild case of manic depression) where I was in a really good, energetic mood, but at the same time felt like if anyone ticked me off, I'd go into a rage
