“science” is not about Truth but just another interpretation of our human world view
But science is systematic, observable, reliable, repeatable and more importantly testable within our current understanding of the universe.
A ghost cat on the end of your bed, however real to the person who saw it, is certainly none of the above, especially testable; it is a matter of faith, of which I have none unless the subject matter is systematic, observable, reliable, repeatable and testable.
