Do Western Christians confuse Mysticism with Emotionalism?

I repeatedly hear Western Christians repudiate mysticism. This post is NOT about the merits or dangers of Christian mysticism. Another question addresses that sufficiently. This question deals with whether or not Western Christians are accurately defining mysticism. It seems that what is often called 'mysticism' by Western Christians is actually what might be better called 'emotionalism.' This is evidenced by the fact that mysticism always seems to be presented as the opposite extreme of rationalism (which implies that mysticism must be irrational). It seems that the trend of creating this dichotomy began historically in Western culture in the Romantic period. But is mysticism the same thing as emotionalism or is this a false dichotomy that we have inherited from Romanticism? Why or why not? If not, what definition would you offer for it? Any sources from Christian history (east or west) would also be appreciated when addressing this question.
