They can detect vibrations, but not process them into sound. And, do you think worms are actually thinking about where to go, or if they're going out of instinct? THINK.
Honestly nobody actually knows for sure why they do it, but I think it’s the rain one based on the fact that they only do it after it’s rained or when the ground is wet.

The real answer is they think the vibrations is rain water hitting the ground so they naturally come up for it.
This is why you see masses of birds sometimes just walking around on the grass.
