I've never thought of "fear" with this kind of connotation. I do agree that it can be described as an expectation or anticipation that has to do with coming disstress or even dis-ease or just the thought of pain. You can be calm through fear. Right now the biggest fear for me is that I'm used to not reacting implusivly, and not letting feelings like fear, lust, anger, etc drive me as they should a human. It may be freedom at a higher level, but sometimes I wonder if you need these feelings to truly be alive and also make good fool-hardy mistakes :-).
