Here's the thing, it is, and you are. Even since the time of the Greeks, there has been Plato's allegory of the cave. None of use come into contact with "reality" proper, and everything you've ever perceived is just your brains best approximation of what was evolutionarily advantageous to your ancestors to survive, and nothing more.

I remember the first time I put on a headset and experiencing not so much actual nausea, as existential nausea, realizing that my locus of perception could be entirely divorced from my proprioceptive sense of what my body was doing. It's less jarring to me while waking, but it completely changed the way I perceive my dreams forever.
