Scientific Method Must Expand - Part 2

If you haven't read part one yet, scroll down a bit.

Since no scientist can prove we dream, yet everyone agrees that we do, our scientific method is incomplete. A scientific method must encompass all we experience, not just what we can intrepret through our five senses. None of our five senses are at work when we gain knowledge from our dreams. That knowledge comes from beyond our physical environment. What scientists currently classify as reality, is really the physical reality we live in during our waking hours. This is the reality we interact with using our five senses. There is at least one other reality, one in which we gain information in a different way - this is the dream reality.

This begs the question - how can science study areas not associated with our physical reality - and all come to agreement on what is discovered?
