The ending is neither confusing or Dr Mabusian - just one that has been used before. I saw it coming when the Psych staff arrived. Notice that at least three of the people at the mental hospital - the woman who comes to get him, the doctor and his wife - are the same people who were supposedly in the steam room. That makes the ending quite clear. Val is having another hallucination. He has used people that he knows from the mental hospital as characters in his Chaos scenario. The 'human chaos' that the doctor refers to is that residing in Kilmer himself. A very stylish film with an excellent cast. Only real problem is that the violence was gratuitous. They could have implied rather than show the more gruesome things.
