  This is an extended discussion of Ref.[1], presenting a nonlinear dynamical
model of quantum collapse, with randomness emerging from self-generated noise.
Here we focus on a few issues: 1) the way chaos theory explains "deterministic
but unpredictable" as a generic feature of nonlinear dynamics; 2) a new
argument about why Bell-CHSH and GHZ experiments confirm quantum mechanics; 3)
a discussion of why the heating effect predicted by CSL-type theories is not
expected to happen according to our approach; 4) in looking for direct-product
solutions of our nonlinear Von Neumann equation, we use a parametrization
different from that used in Ref.[1], allowing better insight to the locality
issue.
