Actually, in special relativity, if you could somehow travel at light speed, your own proper time wouldn’t pass at all. The journey would be instant from your perspective. You’d experience zero time between departure and arrival.

That’s not just "relativistically instant", that’s literally instant in your frame. The time dilation becomes total at light speed, and length contraction collapses the entire distance in the direction of travel to zero.

Now, it’s true we can’t really assign a rest frame to a photon, so this is a thought experiment. But if you extrapolate the math, the conclusion holds: no time passes for something traveling at light speed.
