Dream
 

...... i climb up planks, warm myself by light, then try to get on gantry/walkway to my left, its not happening. its like a barrier is there.
i can get on to the right walkway, but what for ? there are stairs there..I have looked thru walkthroughs and it just says to walk up planks warm yourself, the continue up the walkway ??? thank you ahead of time

Watch this walkthrough video (end of the first movie).
