You chose to stay in the room

Level up!

You move to the dusty corner of the room and sit down. You wonder if maybe someone is just playing a cruel prank on you. Or maybe you just having a bad dream. Just as you begin to consider these possibilities, you notice a purple swirl about the size of a dinner plate form in the center of the room. "What is that?!", you question audibly. Then, the purple swirl begins to grow at a rapid rate and you come to the realization that the swirl is a portal. Do you jump into the portal or do you get out of the room and while you still can?
