trying to get some keys

I dreamed I was in a very big house. It was like a maze, though. Three others guys, who I dont know, were with me. Each room was went into had a different puzzle to get to the next room. But kind of like a haunted house because when we would get to a door, the wall would close right when we got to the door and we had to figure out how to get through. Then we came to a different door which looked like a tomb. Well they all kind of looked like tomb doors. I was by myself because the others had ran past it. Then God stopped me and said "do you want to repent?' I said yes. Then for about 10 seconds I felt incrediably peace. But I said ok I have to get out of here and get that key. Then all of us got to the point to where we were running in circles, I stopped them and I said why don't we try to get the key and they said ok. We came to this tomb looking door and the red light came on and the door opened. Inside was water, bit of food, things to help you survive for a bit. Then I woke up.

I never did see a key, but for some reason, I feel like this dream is important.
Thanks to anyone who can help.

Yes it was peaceful, I just feel like God wants me to see something and I don't know what it is.
