- Of the realms seen Hell is the only one seen in a dark demeanor reflecting its purpose as a place of torture.
- Earth and Purgatory are the only known realms where everything is tangible and existent. Avalon is unseen and Heaven and Hell are mostly memory reflections or illusions of torture and pain.
- Dean Winchester is the only known being to have been to all realms of existence (except The Empty), while Sam, Castiel and Bobby have been to all but Avalon.
- Castiel has been the only being so far, to been shown to have come back from The Empty after he demanded to The Shadow to release him.
- This was later confirmed in Byzantium, where it is stated that he is the only being to ever escape.
- Heaven and Purgatory are the oldest of the realms, followed by either or Earth and then Hell. Paradise existed, soon chaos rolled in, and then when evil came Damnation was created.
- The Earth realm has the most beings walk through it; Purgatory and Hell being second with, monsters, demons, humans, and reapers/Horsemen. Heaven has the least with the least angels, humans, and Horsemen.
- It is currently unknown if there is one God who created the alternate realities, or if there are also other versions of God, or if they were created by him at all.
- Given that the Shadow, the ruler of the Empty, has stated that not even God has power there, it is unclear how God managed to resurrect Castiel so many times.
