What is it like to live in a four-dimensional space? Tell me more.

In fact, like the life of ordinary people, it is nothing more than going through a wormhole and going to the society decades later (I think it is impossible to go back to the past). For example, a watermelon is frozen in the refrigerator and taken out the next day. Watermelon dormancy or time is only a moment, but the real time has passed one day, so it is a four-dimensional space when enlarged. I spent a long time in reality in a short time, that is, I crossed the time axis. Actually, I don't feel anything myself, just a little puzzling.
