Two movies came into my life in the last 4 days… Alex Garland’s Men and David Cronenberg’s Crimes of the Future. Both are from filmmakers I admire and follow closely. Both have been shocking critics with their graphic extremes. One is being distributed by A24 and the other by Neon, the current cutting edge distributors in mainstream but challenging indies.
I don't think Tom Cruise's character is dreaming all of (or even most of) what happens to him in EWS. Kubrick was never one for dream sequences. You may be taking the title of the source novel too literally.
