One of my roommates at time feels the same way Mr InsanePolack. Back when I lived in those old homes I was in an altered state (most of the time) so I would not have questioned seeing freaky things (spent a lot of time in cow pastures picking fungi). And yeah I wonder too-but my scientific mind always wants to find another answer-though often it isn't satisfying. Reminds me of the story of Exodus and the ten plaques-science can explain all in natural terms (they've all happened before) but science can't explain foretelling them before they happened. So yeah I guess I'm skeptical and open at same time. Lots of strange things to contemplate like cosmology and the beginning of universe and weird space-time phenomena or multiverses. Science can't explain everything I've come to realize and some of the explanations seemingly defy logic. The matter and energy in the universe remains constant it just changes form-so what form does all our energy change into-ghosts??? LOL.
