Most, if not all, Dragons live on the Astral planes. They dont hold to any one tradition. From what I've exerienced, they often have a worldview based on respect. You must respect their power, but you must also respect your own too. Dragons hate it when anyone tries to control them. They are very individualistic creatures, so pretense is unwise around them. They are likely to accept you for who you are if you do. This is all general, and each Dragon is diferent.
Grand serpents o dragons, are spirits that represent the calmness and harshness of nature, with the cunningness beyond any animal. They are representative of the sheer elemental powers found in the otherworld.
Whether it's a world serpent of sorts, a dragon deity, or a strong spirit/wight, they all are insanely powerful forces to be reckoned with.
For example, one of the spirits I revere in my practices (via UPG) is the blood serpent, which is an entity that represents the lifeblood of the earth and the leylines. This being could be called a dragon of sorts, and is practically a deity. As a force of nature.
To a smaller extent, I've encountered a winged dragon in the otherworld, and it was still an immense being. Old and dangerous, and quite slow to action.
