I just assume that the warp field makes a crazy visual distortion that makes stars appear to move faster than they are actually moving. The stars are swirling around the warp bubble (that the ship creates) in a weird, illogical manner where some stars that have already passed the vessel are visible in the front of the ship, and vice versa.
It's just a visual clusterfuck of stars due to light distortion from the artificial space-time bubble created by the warp engines, and thank god that the Enterprise has sensors to navigate during warp, or else it'd just make everyone dizzy trying to figure out which direction to set a course in.
Or something. I've had a glass of wine and I feel like my brain
is trapped in a warp bubble at this very moment.
