Depends entirely upon what is smelt, what emotions surround it. For instance, you can say ‘I smell a rat’, or something smells fishy or the whole situation stinks to high heaven. A perfume can remind you of a particular person, and therefore associate with your feelings about them, or with particular memory or events in life. Odours often represent feelings, attractions, repulsion, fresh or stale, living or dying. They can also represent feelings radiating from you, or from what the symbol depicts.
