What does it mean when you dream about your sister and you pushing different pause buttons for the same TV and the fire alarm goes off?

It means that you and your sister must be involved in similar struggles or trials in your life, perhaps even a trial or conflict together, and you would like to just quit working toward whatever goal is at the end of those struggles. However, despite this, your subconscious can sense that something dire would happen if you were to stop, and that in the end quitting would solve nothing at all.
