A dream of a fly or flies generally represents a minor problem or obstacle that you must face. It means that you are being annoyed and irritated by friends or others and that you are perhaps contemplating a foolish action as a result. Flies in a dream also represent delayed success.
Dream flies may symbolize individuals or events that stop you from getting what you want, or they may indicate that you are experiencing frustrations and annoyances at the present time. Because flies are so annoying, they can suck any enjoyment out of an activity or situation, so you should try to determine what things in your waking life fit this description. If you can successfully get rid of the flies in your dream, while dreaming, it means that you will find a way to overcome the annoyances in your “real” life.
Flies in dreams can also represent feelings of guilt or a plan that has broken down. They sometimes predict a contagious illness or being surrounded by people who do not have your best interests at heart. If you dream that you kill the dream flies, it means that you will regain your previous honorable position after “falling from grace” and that you will regain the love of your romantic interest.
Dreams of flies can also be linked to a sense of nervousness you feel about something in your environment. Things like gossip or other social aggravations. If you catch flies in your dream, it indicates that you must avoid stress on your job and not allow other people to make you nervous there. The chief interpretation of insects that appear in a dream involves the fact that you are being annoyed – “bugged” – by something or someone.
