To dream of a canary represents happiness, feeling content, or total satisfaction with the ways things are. A situation may be providing you with everything you need.
To dream of a dead canary represents spoiled happiness. You may have been too comfortable with a situation, or are experiencing bad luck. A carefree situation may have been ruined.
Negatively, may reflect an inconsiderate attitude about discussing how happy or lucky you are are around people that aren’t happy or lucky.
Example: A woman dreamed of seeing chirping and wearing pendant necklace. In waking life she was very happy discussing moving from her home and having lots of money to do new things with the family while not having any serious drive to sell her home in the way she discussed.
