Nocturne, by Jane Reid

I dreamed I was in a house that seemed familiar, but not quite. I had an appointment; it was time to leave. I headed toward the door. But I didn’t find it, instead, another hall opened and I was back in another familiar room. I walked toward where another door should be, but it led to a completely closed-in porch. Puzzled, I looked out a window. The surrounding garden shrubs and nearby buildings were not what I expected to see. 
It was getting later. If I missed this appointment . . . 
I didn’t know why, but I was very afraid.
