Oversensitive Senses

So often it feels like my ears are oversensitive to tone.  Today my sleep was disturbed by the sound of a grating vacuum cleaner.  The residual effects are still haunting me, with an uncomfortable feeling around my chest.  It's like a subtle dull ache that won't go away.  Sound seems to have a literal effect of "touching my heart."  It's a double edged sword, since the most pleasant of sound results in stirrings of bliss beneath...  But the most dissonant sounds feel like knives stabbing, digging into me...
