Recently during meditation I feel as if I can 'smell' myself. Very gross sounding, I know, but that's what it's like. As if I can smell my own gut and insides. I know this will pass but I'm just wondering if anyone has had any similar experience and if there is any meaning to it. I recently did a major overhaul on my diet and went completely vegitarian which suites my very well. Should I do a major clean up? Also, and this is weirder if possible, when I do eye exercises just before asanas I can "hear" my eyes move. A vague yet screeching sort of vibrational sound. Anyone with any similar stuff?
