A true religious person should not think that “my religion alone is the right path and other religions are false.” Other religions are also so many paths leading to the same domain of transcendental bliss. Likewise, no person should think “my perception of the reality is the only absolute reality, and all others’ are false”, because each human brain has its own unique way of perceiving the reality.
In dreams you don't need to make any distinctions between things. Not at all. Boundaries don't exist. So in dreams there are hardly ever collisions. Even if there are, they don't hurt. Reality is different. Reality bites. Reality, reality.
With or without 'college' we are able to use our senses by perceiving the world around us, that in turn shapes and creates ones own reality. Perception is reality. My 'reality' is not the same as your 'reality' since we all have a different mental database, life experience, physiology, different characteristics, environments we grew up and people we hang out with, etc. I might fall in love with a certain smell while it triggers bad memories for someone else. Same goes for the other senses while perceiving 'reality'. And how real is this so called 'reality' anyway? Our senses can be quite limited compared to a camera or other living creatures on the planet. There are sounds and colours humans can not detect with their senses. We in fact do not perceive the whole 'picture'. The most important things in life are unseen. My point is that we do not need hierarchic, indoctrinating, and capitalized institution called 'science' to tell us what, when, why, and how to think, experiment, sense, and live our lives. Long before there was any 'science', there was sense first.
