Crossing An Entity’s Hallway In Another Dimension?

Description: English: MIT Building 20, wing A, looking along the hallway

My urologist Dr. K was possibly in a forgotten part of this dream, I am not sure.

I do know that during the end of the dream I was inside a building with my mom and a woman and several other people.

At some point, the woman found a door that led to a hallway with doors on both sides of it, with maybe a final door at the end of the other side of the hallway.

The door that she found possibly led to another dimension that the hallway was in, or it was just another part of this building.
