What if there were 2 sides of a mirror. What if your reflection wants to keep you on the other side? What if you are able to climb through a mirror, but your reflection keeps standing in front of you, blocking your way. Try to touch the mirror without your reflection touching the same place. Maybe the cold surface isn't the mirror you are touching but the cold flesh of your own reflection, pushing back keeping you inside. Think about that, maybe you are the reflection.
