If you want to experience time dilation as physics describes it, you don’t need virtual reality. Because no matter what, you always experience time local to you as one second per second. Time dilation doesn’t change our perception of motion.

Satellites have to adjust their atomic clock by some very small percent to stay in sync with us, because they are accelerating to stay in the right orbit. So that’s the extent of time dilation we could have practical access to.

But that doesn’t get to the salient point. The point is, if you had a twin who went off on a spaceship and experienced enough time dilation to get 1 second for every 2 that passed at home, and somehow didn’t have to worry about being squished by the extreme acceleration, he would come home in a year to us, having only lived for six months to him, and everything in his point of view would have moved at normal rates.
