I need help making up metaphors for things I've seen. Like in a forest I saw a single red cardinal as if it was the happiness within the gloom. Also there were two fallen trees, one above the other as if two fallen lovers & the one bigger one above was the husband protecting the wife. Maybe love is like a battlefield? Along with random things like a beer can at the bottom of the pond & a piece of metal in a dead grassy field...
