What is a dryad?

Answer 1

Dryads (Tree spirits, Tree Ladies, Druidesses, Hamadryads, Sidhe Draoi): These færies come from Celtic countries but are still a worldwide phenomenon. Their element is air, contrary to what may be believed. These particular færies are active all year but are most active at full moons. They are tree dwelling spirits from whom the female druids took their name. These creatures are only referred to as female. They are playful creatures but only seen as enchanting wisps of pure light. When a dryad does make contact you can't be sure whether they are there to help, play, or tease. If they help they are supposed to help you contact divine forces or even work on your magical abilities. They play wonderful music, as well as sing it. No one yet is known to have been harmed by following the music but it may cause you to stay too long in the astral world. If you want to find them go to a grove of trees, preferably with sacred trees of the druids such as willow. Maybe oak, ash, thorn, rowan, birch, and elder trees could find them near. They might be found in the physical plain but also, and mostly in the astral.

In Greek mythology, dryads were considered tree nymphs.
