Okay so you know that you can probably move... a little each time you were recreated before the destruction. It takes an incredible amount of focus and you had to let the scream lie in your stomach. You notice through your slow gradual pain-staking progress that there are indeed others in this room... also caught in the same process that you are. You only can see them for a second before they are gone again. You suspect that the less you resist the faster the process. You are resisting and so the process was slower for you. So force of will was a form of power here, knowing that you are able to resist even further; feeling the process slow.
Realizing this trick you are able to get past the room and into a tunnel. The effect continues though and it does feel like it is wearing on your soul. However you know if you stopped fighting it like you are that you could lose yourself in the loop. Moving always moving you are finally able to get to a new chamber and the moment you step in the pressure is gone. You finally are able to scream and you do just that. Unfortunately apparently there are others in the tunnels and you can hear them yelling and coming towards your chamber.
On the positive side a new ice portal forms and you are clearly going to be allowed to move onto the next layer.
