A flea is a small wingless bloodsucking insect that feeds on warm-blooded animals.
Positive: In a dream, a flea could represent God trying to get your attention.
Negative: Dreaming of a flea could symbolize something that is not substantial, annoying, subtle, inconvenient, or an insignificant challenge or circumstance. It could represent a person who fleas from certain situations. It could also indicate a person who wants to provoke or manipulate you to retaliate in anger.
(1 Samuel 24:14).
