I forget the exacty location, but in a bar-like room probably halfway through the level there's some LED advertisement lights that hang off the wall by a few inches. It's possible to teleport directly against the wall and get partially stuck in between the wall and LEDs. I was able to get out by teleporting carefully up the wall until the LED no longer obstructed my view, but I almost died when a bunch of enemies attacked me as I was trying to get out.
