Dream about church. Help me to interpretate

It dreamt that I was with group of people. We were going to omnious looking red church, which from outside seemed like a muscle and insanely tall. The only way to get to the door was go up with a single rope which is controllable. When we opened the door, we saw red luminating stairs leading to complete darkness. When we went there, there were demonic looking creatures were living. It was place that a door opens and closes itself. I was having deja vu several times which helped us to survive without dying. Finally, a devil who isn't that bad taught us how to kill a demon. It was to stab a particular place twice. We killed every one of them, then the strairs appeared again and we went to real world.
