Levels of emotional experience

Emotions are experienced at multiple different levels:  Biologically, behaviorally, and experientially.  I believe that many people think that because their experiences are unique, that makes their emotions about those experiences unique, and therefore, unknowable.  That there's no basis for comparison, so nothing can be learned from, or about, their emotions.  I believe that this is not only wrong, it's also incredibly damaging.  It prevents us from learning about how our emotions work on a biological and a behavioral level.  And there is much to learn about emotions on both the biological and the behavioral level!
