While Fae overall have MANY meanings, Fairies usually symbolize a deep connection between living beings and nature. They can be humorous and tricksters by nature. With their ability to fly, they are free spirits, and are usually naïve to the evils of the world, they would rather laugh than find real solutions to problematic and serious situations.
Seeing a fairy in a dream could mean that you are about to receive great news in an unexpected or thrilling way. Since the fairy can symbolize love and affection you could be on the cusp of getting a proposal. Or that you will be having a child soon.
