Life would be normal for you. But the rest of the universe would be running on fast forward.
Maybe a civilization could use these stars to spread itself to other parts of the galaxy or, if fast enough, to other galaxies.
You have to get into the 90% range for something meaningful. Even at 96% the speed of light, it’s a 4x speed difference.
99.99% is 80x time difference. 99.999% is 240x time diff.
To have time speed up to the point of civilizations rising and falling in a matter of days, you’d need to be traveling at 99% (with a few 9s in the decimal places). Though at relative speeds that high, it would be difficult to actually see what’s happening.
Here’s a calculator that’ll show you time dilation at different speeds https://keisan.casio.com/exec/system/1224059993

Nice use case :D
You may be confusing it with red shift.
If a hypervelocity star passed by us, we would see them in slow motion because they are moving at high speed relative to us. At the same time, they would see us in slow motion because we would be moving at high speed relative to them. The effect of “the other clock is slower” is reciprocal.
The weirder and non-reciprocal effects would occur when the hypervelocity star is first slingshotted out to high speed. At that point they would be close to a black hole (deep in a gravitational well) and accelerating (non-inertial frame of reference). Under those conditions, their clock would run slower than our clock for observers on both sides — i.e., we would see them in slow motion and they would see us in fast forward.
You see a lot, but your face would be caked over with bugs.
IOW, a planet like that would have a much larger chance of colliding with interstellar debris. Then again, there is probably very little of that.
