Lvl 4/5 - Trials of Thought - My thought machine don't work

Thanks Drax.

Ok I have a three questions:
1. How do you open the door (near area 1 on the image)? It is one of the areas you fall in during solving puzzles on level 4.
2. What does the button on the wall do? The button is in the area where you have to quickly walk across closing pits (point 2 on the map).
3. How do you open the iron door towards the end of lvl 5? Says sleep in front of dragons, found two, slept there, door stays closed.

Why does the image not show?

You linked to a webpage, the actual image is "http://i.imgur.com/K3DcX.jpg"

1)You'll, um, drop in to that later on.
2)It raises a platform nearby so you can grab some bracers.
3)Don't rest in front of each dragon, rest where their gazes meet.
