Dreaming of a smell often implies an actual physical sensation. Your nose may be picking up an odor that really exists.
It’s important to be aware of this, especially if the smell is that of smoke or gas.
Try to condition yourself to wake up whenever an ominous odor appears in a dream.
If this isn’t the case, dreaming of pleasant odors such as flowers, the salt air, or good food cooking symbolizes good times ahead, usually associated with whatever is giving off the odor.
See Flowers, Beach, Coffee, etc.
Dreaming of unpleasant odors is a sign that something is being kept from you – as in the old saying, “I smell a rat.”
