Hi Sunny . A 3 Headed Dragon would be the hydra or a thessela~hydra ..
The actual 3 Headed Dragon of game mythology was the Chromatic Dragon
known to the game Dungeons & Dragons .. Her name's Tiamat and she's uh
quite evil .. the opposite of Bahamut ., a Very Good Platinum Dragon of the:
Seven Heavens of DragonKind . If the picture you did see while meditating,
was one color it would not show she's got three different color heads . . . . .
The Thessala~Hydra or Thassalaco~hydra are sometimes seen with many heads
or without a central head .. rather a neckless maw at the center of outer heads...
I say you did see a picture of the griffin ., related to the horse bodied hippogriff ..
and the 3 Headed Dragon was a terror of evil named Tiamat. It's in the game.
Evard ~ a Game King really .. United States King I guess .. OK Thanks. AM aste~
