I am at the second dream sequence, on my way to Galbadia Garden.

I have gone down to the reactor-thingy - down the staircase, gotten (and lost) the key, hampered with the trap door, gotten (and lost) the second key - and now I'm stuck. I'm supposed to find a room with two switches, before ending outside near a cliff! But I just find two screens of corridor, where one ends in a long staircase that ends up where I started.

Can someone please help me on what to do here? I've have read three different FAQs without finding those switches and progressing with the game.

Help will be greatly appreciated!
