Dream of

I was taking a trip on a train first i went and got an elevator to go get on the train as i got off the elevator i was walking down the corridors i saw other people also going to get on the train to travel , then .something someone said made me notice that I didn't have my purse with me so I went to get back on the elevator to go back home and get my purse and hurry and come back to catch the train in time.
