Crawford's fate
I assume that Katherine is destined for a mental institution. From that laugh she seems driven totally insane from either her pineal gland being stimulated by the machine, or the ghastly sights from beyond (likely both).
But what is even more disturbing to me is contemplating Crawfords' ultimate fate. He seems left forever in the other dimension, occupying the same shoggoth-like body that Pretorius inhabits.
Is he destined to spend eternity battling on some mental/physical level with Pretorius in this new bizarre form? Will he eventually be able to separate himself from the body they both inhabit? Would they stop fighting at some point and make peace with each other? Will their intelligences merge into a new, hybrid being?
too creepy.
