(see Flying)
Dreaming of a fly, that is, the insect, represents a minor obstacle that must be overcome - in short, the proverbial “fly in the ointment.” An annoying fly that keeps buzzing around your head is a signal that the obstacle, however miniscule it might be, will not go away on its own and requires immediate attention.
Interpretation 2 — Klaus Vollmar
Folklore: Sign of an unsurmountable obstacle.
Interpretation 3 — Ariadne Green
A fly on the wall may come to say that much can be learned by observing.
