When you can see with the Third Eye (Second sight) you begin to perceive beings in the Astral Realm. These entities have been known as many things over the years, Djinn (in Islam), Faeries (in Ireland), The Shining Ones (in Europe) , Extra-terrestrials (in Modern Day Folklore) and Demons (in Christianity), but the ancient Gnostics called them Archons, which David Icke uses. There is a detailed history of these beings which can be found online by searching for Daemons in Greek mythology on Wikipedia, or following some of the Website Links on this site towards Occult literature.
