Fairies and the fae are notorious in folklore to be interconnected with the moon. The old tales depict them as tiny winged creatures that are especially active during the new and full moon cycles. As the moon is full, it is said that the veil between our world and the fairy realm is very thin.
This could mean that maybe those little sparkles we see out of the corner of our eye during these lunar cycles could be the fairies dancing about. What do you believe?
