Book of Dreams

It's really hard to record dreams in the morning on days I have school, so this is just what I can remember.

I'm in a big church for mass, and afterwards, I'm trying to find my way out before the next mass starts. I make my way into the small narthex, then down a flight of stairs into a sitting room, which also looks like a makeshift chapel. The procession is making its way through the sitting room toward the stairs. To the right is a great wooden door with stained glass windows. I ask a man near the door if I may exit this way. "Well, the customer is always right!" He says. I then leave and run down the paved parkinglot to the car. Someone is driving me, and while I'm on the highway I realize I have forgotten something in the sanctuary. I tell the driver to turn us around and head back to the church. Then I get a text from Kelsey asking me where I am. Apparently, I was supposed to go to mass with her and her family at the 9:30, but I already attended the 7:45.
There is a cut-scene where Kelsey and her family arrive in a white car, and Kelsey exits the car wearing a fluffy white dress. Her parents, normally dressed, follow her into the church.
I sneak back into the sanctuary through a door next to the altar. I spot Kelsey and her family in the pew where my stuff is. I try to sneak in without them noticing. I don't remember exactly how it happens, but Kelsey notices me and begins chasing me all throughout the building, yelling at me for ditching her mass. Near the end of the dream, I realize we were supposed to get married. Oops.
