Astral Projection is a quite rare ability to extend at least a portion of your body outward to the astral world.
Projecting one's true self can be harmful and chaotic to the outside world, like when angels extend their true form. If a human completely leaves their body, they become much like a living ghost, gaining all the powers that ghosts do (Super strength, Teleportation, Telekinesis etc.) but only after plenty of practice.
Characters with this ability
- God - He revealed his true form to Metatron.
- Angels - Castiel projected his wings to Dean to prove what he was when Dean didn't believe him. He did this again to Crowley during a match-off. While possessing Sam Winchester, Gadreel projected his broken wings before killing three of Abaddon's demons.
- Seraphim - More advanced than Angels
- Jack - was able to project his awareness into Michaels fortress to discover that it was in fact empty. He can also display his wings.
- Death - Demonstrated when he was liberated by Lucifer.
- Witches (via Magic)
- Dean Winchester - While acting as the vessel to Michael and powered by the archangel, Dean was able to display Michael's wings after teleporting to the church where Lucifer, Sam and Jack were.
