Omnipresent 'music' at stratospheric volume levels, car engines, car horns, people screaming, construction sites, etc. Sometimes, when I'm back in home, after all this noise, I don't want to listen to music, I just want silence and dark. I find the silence experience in those cases almost as a tranquilizer drug. I think I may be hypersensitive to noise pollution, few things can put me in such a bad mood, sometimes to the point of physical discomfort, like heartburn. I can't think properly, I just want silence.
