It's not Freudian dream theory (which the virtually most psychologists happily agree is not science), but it's not experimental psychology, either. Unlike dream theory, though, it still claims to be science. I agree that the question is a scientific question, but there is a difference between a scientific question and a scientific endeavour. If we don't have the science to answer a scientific question (e.g. about multiple universes) we call our thought experiments and hypotheses pure speculation; we don't try to present them as carrying any sort of scientific validity.
