Dream interpretation request

So I've been having these weird dreams for the past few weeks. Basically, the storyline would be entirely different per dream (though all of them partly or wholly took place at school), but within each dream, there would be a scenario, and I'd play through one outcome of the scenario one way, and then it would rewind and then I'd play through another outcome of the scenario, without realizing that it rewound. I don't even play scenario games. Does anyone have any idea what this means?
