I am now watching the movie Perfume.

Yes. Another story about the disturbed mind.

There is one part where this poor Jean-Baptiste Grenouille suffered alone battling his mind because he couldn't find his own scent but could extraordinarily 'capture' all others .

I guess this mind battle has been going on for ages.

We use our entire lifetime trying to make sense all around us, that we can't find our own 'scent'. We have either lost that capability or ruin it ourselves.
