(Psychological / emotional perspective)
Our sense of smell is extremely delicate, but just as the other senses such as touch and sound are suspended or transmuted into something slightly different in dreams, an odour in a dream may be a way of reminding ourselves of another time or place. Odour is highly evocative and for the dreaming self to register a known smell or perfume suggests that we are trying to make some sort of connection with conditions we have known in the past.
