[Chewbacca]

When you first walk into the room, rays of red light coming from the pillar were touching certain squares on the floor. After activating the pillar, the lights dissappeared. The light rays are the key to this puzzle.

The key to getting out is to only walk on the squares the red lights were not touching when you first enter the room. Its kinda like the game concentration, you have to remember where the light rays were and weren't touching or get real lucky, or maybe even (worse case scenario) reload from an autosave if neither of those work for you. Perhaps someone knows or remembers the pattern and can walk you through it.

As fair as the wailing thing, I dunno what you are refering to, unless you speak of the visual effects coming from the middle of the area, that's purely cosmetic.
