I dreamt about spiders too last night, only they were real spiders and every time I killed one the next one would get bigger. The first one I squished, the next one I killed with a newspaper, than my shoe, than I ran over one with my car, clubbed one to death with a branch and finally the biggest one was like shelob from return of the king, and I killed it by throwing 2 spears through it. I also kept finding 5 dollar bills on the ground. I don't remember what the main plot of the dream was though.
