How would one go about decreasing their fear of spiders through lucid dreaming?

My fear of spiders is ridiculous. If I see one, I'll just freeze and be scared shitless. I accidentally stepped on one just now and it took me 5 minutes to gain the courage to pick it up and put it in the bin even though it was dead. If there's one in my room and I don't know where it is, I won't go in my room at all. I just need help and I don't want to confront my fear personally because it's that bad so I figured lucid dreaming will probably help
