Actually, your explanation is rather confusing. But if that's the way you see it, fine. I must point out however, that while you provided an explanation for all of the dead in the other dimension, you forgot about the living. Trubel, Diana, and Kelly were in the same plane as Nick. I noticed you mentioned Diana, but you have no explanation as to the reason they were left behind.
