The dungeon layouts change between playthroughs, so you're definitely not guaranteed to have the exact same path as somebody else.
What are you trying to do? Where are youbtrying to go? We may be able to help you, since the dungeon configurations are somewhat limited. But your best bet might just be to explore the area yourself (that is part of the fun of this game, at least for me!) and look for the object you need all over the place.
I can give you a tip that may be helpful, though: Certain indentations in the walls are actually doorways, or even closed doors. If you see a place in the walls that is deeper than the walls around, walk into it, and if that doesn't work, press enter on it!
