In no particular order:

    Impro: Improvisation and the Theatre (Keith Johnstone)
    The Master and His Emissary (Iain McGilchrist et al.)
    Emissary’s guide to worlding (Ian Cheng)

Black Swan by NNT already recommended elsewhere in the thread.

I want to go off-topic and recommend a non-book, Learning to Fly by Missing the Ground[0] (Venkatesh Rao).

And further off the topic, the discussions in The Midnight Gospel were the closest to qualifying as mind-bending experience recently.
