What racial features can a Kalashtar use while wildshaped?

As the title states, I want to know which racial features, if any, of the kalashtar are usable in wildshaped form.

The traits are named as follows: Dual Mind, Mental Discipline, Mind Link, Severed from Dreams

Both of these questions are related:
How do I determine if a Racial Trait applies to Wildshape?
Does a wildshaped druid retain his/her racial resistances?

This was a question I thought of when looking at this question, as a way of communicating to the Bestial Spirit: Is it possible to combine Summon Beastial Spirit spell and Wildshape to travel by air?
