Dreamland

Those are some interesting dreams! The first two, to me, seem to speak of power. Either you realize you have power (in awake life) or perhaps wish you had power. You also got everyone's attention in those first two dreams.
The third is completely different! The maze of the school could reflect confusion or a sense of being lost or helpless. Then you were missing out ... on classes, on friends ...
So perhaps the first two dreams reflect your desires while the last dream reflects your current feelings.
Or, maybe it was the funky pizza you ate before bed!
