Similarly one may ask, what would happen if Anakin Skywalker likes sand?
Anakin Skywalker doesn't hate sand in the sense that the sight of it upsets/scares him. He dislikes living in an encironment that contains a lot of sand, because it is unpleasant compared to what he has become accustomed to. And alternate reading of that line is that he doesn't actually have a problem with sand at all.
Also, does Ahsoka have a crush on Anakin? In terms of sibling love, I say completely yes, Anakin love Ashoka like what an older brother would, and Ashoka look up to him as his big brother.
Consequently, what does Anakin say about sand?
Anakin Skywalker: I don't like sand. It's coarse, and rough, and irritating, and it gets everywhere.
Why is Anakin scared of sand?
But even taking that out of the equation, it makes sense for Anakin to hate sand, not just because it's coarse and rough and irritating and it gets everywhere, but because of what it represents: Tatooine. It is lush and full of life and possibilities, and everything Tatooine didn't have. Sand is a reminder of all that.
