As far as I'm aware (which doesn't mean that I'm correct by any stretch of the imagination) there isn't any in-game attack or ability that lets the user read someone's mind, as far as I'm aware it's only something that can be done in roleplay not mechanically even if there are characters in the lore that are able to read minds.
I can see arguments for having a way to defend against mind reading even if you don't have defense against psionic abilities mechanically, so long as you aren't trying to argue that your character has a defense against abilities that they mechanically don't. I think you can be immune to mind reading if you have a good reason, but if you don't have a mechanical defense against dominate I wouldn't want to see someone claiming immunity to dominate in rp.
