Because I am absolutely terrified of lions. When I was a little girl, I went to the San Francisco zoo with my family. I was forced to go in the lion house by my cousin, who kept insisting the lions COULDN'T get out of their cage, and that it was perfectly safe.
I did not believe her. Lions are terrifying.
So it was kind of odd to be dreaming that I had a lion. In my dream, I KNEW that I was terrified of lions, and that I shouldn't have one as a pet. But the little guy was so cute. He was pale yellow, almost white, and he jumped around a lot, happily frolicking. And he loved me so very much, I just couldn't get rid of him.
(After writing this post, I checked the Dream Symbols Dictionary at Glamour.com to see what my dream meant. Apparently dreaming of a friendly lion cub is a forecast of a new and valuable friendship. Odd.)
