The term Drosoulites (Greek: Δροσουλίτες) refers to a long procession of visions, seen by residents around Frangokastello castle in Sfakia region of Crete (Greece). The phenomenon is rumored to be visible every year, on the anniversary of the Battle of Frangokastello or even in early June near a small village in southern Crete. The local people named them Drosoulites ("dew shadows") due to the time of day that the phenomenon takes place. The phenomenon is observed when the sea is calm and the atmosphere is moist and before the sun goes too high up in the sky. It usually lasts about 10 minutes.
