A Word on "Clairalience"

Clairalience is having the ability smell scents beyond the normal physical sense of smell. For example – you may smell the scent of your grandmother’s perfume even though she has passed away or the smell of a particular tobacco your father used to smoke when he was alive. When this occurs it will bring back memories of that person and also indicate that your loved one in spirit is with you, and trying to let you know they are there. (Source)
