How come angels/masters/deities look human, as opposed to like grey aliens?

Are humans a special species??

In the astral it is possible to shape shift into anything you like. A master will usually choose an appearance that will be easily accepted by a person. However, i have seen some advanced beings that are non human, including ET types.
