Pleiadeans (also spelled Pleiadian or Plejaran) is the name given to what are said to be a group of Nordic Aliens or "multidimensional spirit beings" from the Pleiades star cluster in the constellation of Taurus, approximately 400 light years from planet Earth. Their home planet is said to be called Erra, and various descriptions of their appearance have been given by those who claim to have been in contact with them. Contactees who claim to have been in contact with the Pleiadeans include Billy Meier and James Gilliland ; their reliability as witnesses is disputed.
