Dragon Age Origins, stuck in Shale's nightmare in the fade

OK, so I'm playing Dragon Age: Origins. Yeah yeah, I know I'm slow, I've been playing it since Christmas and I'm barely 13th level. Whatever, anyways, I finally start rounding up my buddies out of their own nightmares inside the Sloth Demon's fade realm.

All is going well until I get to Shale, I can't seem to figure out how the hell to get past this horned arch thing near the entrance. I figured it out after like 10 minutes, kinda stupid and funny at the same time, anyways, here's a video explaining it in case anyone else out there is stuck and getting pissed off like I was.

Warning, adult language in this video... sorry, bad habit of mine.
