In Ocarina of Time I went through the very first dungeon and faced Gohma (Gomah?). Anyways, during the part where you have to shoot her down from the ceiling I couldn't find her, so I started to pan the camera around (in 1st person mode) when she drops down right beind me. Her eye was, like, two inches away and filled the entire screen.
Scary as hell.
