A dragonfly is a symbol of freedom, but also represents that freedom is temporary.
If you see a dragonfly in your dream, it means that you can expect change. It may also be an indication that everything may not be as it first appears. A dragonfly landing on your body signifies good luck and that you will soon hear something good from a friend.
If the dragonfly is dead, it is a symbol of its short existence, but ability to regenerate. If we are in pursuit of a dream, we may lack focus. We may be more likely to run on instinct rather than seek to trust our logical judgement.
