Spiders

This dream had a lot more to it than what I can recall. I was in my house, I think, when I saw a huge spider perched atop some struture. Naturally, I keep my distance and go back inside to let everyone that there was an abnormally huge spider outside. When I came back with another person, they noticed a different spider measuring about the size of a basketball in diameter, legs and all. Shocked, I pointed to the one I had seen which was twice as big. When it started to move, I retreated but then noticed that it had turned into a spider made of legos.
Dreaming of spiders is supposed to be a good omen.
