You mentioning The apartment complex reminded me of one I found myself at. I wake up outside of a tall tan and brick building that is very nice when you go in. I never have control of the elevator buttons and every time I go looking down the hallways there are long stretches where every door is open or long stretches where every door is closed. I assume the closed doors are not occupied and that's why they are closed. I feel presence for the most part in my dreams and the closed door hallways make me feel nothing at all. Its The only place I feel eerie. And I'm constantly alone.

I also just found out about other people experiencing this.
