I dreampt I was riding my bike on rocks in the dark. I was wishing I had a mountain bike instead of what I was riding.  I got to an empty city and I found my way inside a house.  I could hear voices but sometimes where I heard them was where I had been but I could not get back. The doors seemed to lock and unlock at random. All of the windows were sealed.  Some of the doors where in places I could not reach like over staircases in the ceiling. I felt I was running from someone but I also thought the voices were not who I was running from.  I found a family of only children.  The oldest girl was taking care of everyone and their parents were gone.  The parents must have found a way out and not a way back in, or they left deliberately. Everyone was terrified of being separated in the house so we all went everywhere together. One night during a storm I was reading the children a story and there was a ghost of a woman on the outside of the window and we were scared she would come in and take the children.  Everyone ran and of course, things got mixed up with people on different floors of the house.  The house seemed to rearrange itself to keep us apart. When I looked out the windows I never saw people but sometimes I saw things change like one night a house would have Christmas lights up. I don't know how we all escaped but later in the dream, we were all in a field for some sort of festival and we had to climb these very tall trees to scare a mass of crows away. The field was covered in marshmallows and some of the kids stopped to eat them but the adults ran for the trees and climbed up with wasps nests on sticks to make the birds leave. From the top of the trees, we could see that one of the children in our family was eating the marshmallows.  When we looked back again she had disappeared.  The girl never appeared again and I don't know where she went. We reminisced about this later in the dream and years later in life on a phone call.  I was on the other end of the call with the oldest sister who was now married to a man who was helping raise her siblings and their children.  The house was decorated for fall with the banisters all done in garland and leaves.  As we talked the sister looked at a replica of the wasp nests used to scare the crows away.  She wondered where her little sister was and then I woke up.
