Same as title. Just hoping there was a way to play a Psychic Dragon Disciple with the Esoteric Nightmare Dragon as the theme.
Psychic casters can work with prestige classes.
What they can't do is satisfy a prerequisite like 'Ability to cast 1st-level arcane spells without preparation.' anymore than an Oracle could.
Physic is not arcane any more than divine is arcane.
There are precious few prestige classes that work with psychic casting. :(
If your GM’s cool, you can ask them for permission.
