Whose ruler?

Dream: I was in a school class room. A teacher with a blond hair asked the students about a missing & found ruler. She announced that the owner would get the ruler back if he could prove that it is his/hers. One student, Toni, rose and went to the blackboard to draw a picture of "his" ruler. It was light blue, had jagged edges and it had some kind of a wolf face on it.

Analysis: This let's-identify-property most likely came from a real-life event in school where there was an announcement about a lost car key. No lucidity in sight.

But boy, I'm happy! Now, after a long pause, I've started to remember dreams in their whole glory again! ^_^
