I think it's "time traveling forwards happens slower the faster you move."

The easy explanation is that we're traveling in a 4 dimensional space at the speed of light, and any increase in speed in the 3 spatial dimensions must subtract from your speed in the orthogonal time dimension.

Maybe in an Orthogonal Universe [1,2], but not in ours :)

The way you state it, traveler's time would speed up (as the resting frame's time of journey would be decreased).

If I jump on a ship and travel near light speed (Not possible yet) and then land on the same spot I would not have spent the same time as those on the earth.

Now at a tiny level anyone ever on an airplane also will have spent less time than those who never have flown.
