If anyone is looking for more information about locked-in syndrome, the book "Consciousness and the Brain" by Stanislas Dehaenehas has some chapters about a few of these patients. Dehaenehas details how they use fMRIs to communicate with some of the patients. Its a very interesting read.
Errr, Eistein fully accepted (as did most others fairly quickly) that quantum mechanics was real -- in fact the duality of wave + particle for photons was something he developed (as part of his developing the theory that explained the photoelectric effect).
The "does not play dice" was mostly with regard to Heisenberg, in which he was determined to find a way to avoid the predicted lack of predictability of the future.
