I ran across this gem at Reddit Dreams that illustrates how dreams use symbolism. Here is the post (link to original):
So when I finally fell asleep last night I had a dream that a giant green goose with the human face of Ryan Gosling, with hands on the ends of its wings, was chasing me around trying to touch my hair. Also, Gosling had a beak that continued to squawk like a goose. It was … weird.
I wish I was making this up.
So I suggested to the dreamer that maybe the goose was symbolism for how he perceived Ryan Gosling. We all had a good laugh. Then he goes on to explain more of the dream:
My friend told me that a gosling is apparently a baby goose. Then my wife told me that I saw green because I am low on money and he was grabbing at my hair because I am “balding.” Hahaha. Maybe they’re right.
This suggests that maybe the silly goose is the dreamer for worrying about his hair. Gosling is known for his vanity, and dreams love to take these little facts we know about celebrities or otherwise and turn them into stories.
