Did anyone else get this terrifying encounter?

I've seen tons of play throughs, and it seems to be common to completely miss opening the 2nd door, and instead head right to the end of the room, which disables this encounter somehow. This disappointed me, since this encounter is so unexpected and terrifying, and would have made some awesome reactions in these play throughs. I like exploring every single thing before I move on though, and had this encounter. It made me piss my boxers a little, since it was easily the scariest encounter in the entire game. You just don't expect it, and when you see it, the monster's RIGHT in front of you, right in your face.
