I'm at the part where you get Morpheus's black key and enter the secret door. I read that if you wore your robes, you wouldn't be troubled, but when I go in the door, the whole base is alerted and goes into combat mode. Is there any way to avoid having to fight the whole place?

Ya suppose to kill Morpheus, I assume. That or ya can just let him lead ya to his master right away for pacifist run. Still keep the robe on when ya done with Morpheus.

Err... I didn't even have the robes before I killed Morpheus. I got them from him.

The second I open the door, the nightkin spots me. Anyway, I ran past him and went down the stairs into the cave, so I think I'm fine now.
