I agree with others in this thread that pleasure can be transcendent or a political act of reclaiming the self, where taking or losing control is a means of opting out of the banality of mass media or norms of behaviour, or that simply having the experience of feeling something entirely good (pre-comedown) can be perception changing. Pleasure can be a rite of passage in this sense, or the experience of sensual intensity can help develop an appreciation of the mundane, smoothing the way for a deeper, more socialised rhythm of life with family etc. Sometimes the dance/drug ritual is used to extremes almost in order to purge (or numb) the pleasure impulse/addiction.
This can become a prison, though people can get stuck at any point in their lives. Most people who get into clubbing seem to do it for a bit, get bored and move on.
Could it have ever been something other than what it is?
