Feels like one is traveling rapidly through space. The planets, then the abyss of space, the stars, the nebula all whipping by.... but in ones on reference frame everything is slow. Looking out , seeing one's half reflection in the glass. Everything that one knew, faded away.
And then you smash into something at near the speed of light (chrrrr at the end)
Nice desaturation at some points, really kicks it home.
