What is this orb?

Your sims are living near good school. In the other words, "Good Schools" lot trait is the reason to this. I have seen this too. Child (or teen) gets a confident moodlet and then this orb appears with rainbow. Rainbow disappears and only orb (sun) will stay. After confident moodlet is gone, the orb is too.
