I guess it would depend on the severity of the mood swing, ie are you looking for severe manic behavior or really bad depression. There's a difference between having a full blown mood episode versus a varying mood that doesn't go to any extremes

What you describe sounds like an episode of psychosis that happened outside of any type of severe mood swing. That's typically what happens in Schizoaffective Disorder.
