Keys In The Abandoned Town

I dreamed that I was in an empty town with three other people who were supposed to be my family, I guess. There was a dad who I remember resembling the dad on the movie Disappearance, a mom, and a son. I was the daughter. I kept finding keys everywhere with color coded tags and was taking pictures of practically everything. I remember my brother and I were looking around by what turned out to be an old mental asylum for women when I found the first ring of keys hidden behind a metal door. It had several keys, each a different color, which I quickly realized was for each different area of the town. I think yellow was for education,  like the schools, and green was for health, like the women's hospital. I left my mom and brother and found my dad in a print shop freaking out about a picture that had printed made of blood or something. He was calling someone, some woman, who I somehow knew he had a crush on or would develop one because as part of the plot he and my mother didn't feel for each other like they used to, and he was going realize he still loved her by the end of the dream. I found another set of keys inside of a printer with tan stickers or whatever and took those and started trying to open things in the print shop. All the while the woman my dad had been talking to on the phone had already made up her mind to come find us in this town to help is settle whatever was going on. I started trying the keys in random locks around the print shop and just as I found one that fit, I woke up.
