Yes, you can clearly see a fourth spatial dimension, in the same way the Flatlander did. Just have someone from the fourth dimension, push you out of your three dimensional world and take a look around. - everything will become crystal clear. But then, I suspect that once you are placed back into your 3 dimensional world, you’ll suffer the same fate as the Flatlander. As time passes, you’ll forget how the fourth dimension looked and your whole experience will be fuzzy and confusing, also, you’ll have an impossible time trying to explain to someone else, just exactly what you saw. After all, for a forth dimensional person, it is a trivial matter to look inside a room that is surrounded on all sides by walls.
