Dream of hands, shopping, toilet

Shopping with a friend for a black dress/coat. She had seen one in a shop for me but when we got there all the black dresses/coats had been sold. We decided to get train back home but missed the last one. I told my friend I would drive her home but she said she would get the train in the opposite direction to Thornside and then get the train to Petrie. Her daughter was with us and I needed to go to the toilet. All the toilets at the station were locked so my friend said there would be a toilet on the train. When the train came it was one that had an upper and lower section but as I kept going down to look for the toilets I said "There's 19 levels". We didn't find a toilet so when the train stopped I went out and found a grassy spot. We got back on the train and headed to Petrie. As we went over the bridge we were able to put our hands out and feel the water washing over them and water splashing on our faces. It started to go up and down like a roller coaster ride.
