Remembering Dreams

Not gonna say every dream is a paranormal event but, what confounds me is i remember distinctly what Hale-Bopp looked like in the sky and what i viewed in the dream was nothing like that. The comets were much larger and orientated differently throughout the sky and the car in the dream was not the one i own, ever owned nor would own lol. Like many dreams the setting was in my childhood neighborhood, though on the access sugar sand road behind our house. I guess if i was to view a celestial event, can't think of a better spot as it was very dark back there. So, if dreams are replays of stored memories that are remembered crystal clear, why dream something completely different than what we know? That's where the theory arises another me/same me (another theory) owns that specific car, parked on that sandy road and witnessed a pretty awesome (slightly unnerving) spectacle. With all the unknowns we encounter and science continually pressing on hidden boundaries, is it possible we can travel and/or jump to 'other places' in our dreams? Sure, why not? By-the-book-skeptics would never agree but how many things thought impossible were proven possible? Having an open yet grounded mind is not a terrible way to proceed everyday...and who doesn't enjoy a good mystery? ;)
I love this analysis. Maybe when we dream we are having memories of other timeline experiences. Dreaming may connect us to our higher self that lives somewhere in the cosmic net (or with God). Did I get this right?
