My dream last night

A person in the city is with her friends who are males and they want to go to the beach. They follow the train tracks and then they find a large tree in the way and her friends don't know how to pass it, however the girl has an invisible horse and jumps over it. They end up at the beach but then the girl falls into labour and runs to toilets. Then she gets teleported to a large stationary shop kinda like office works, she puts the baby down and gets some plastic, waterproof stuff which she then puts on. Then she's teleported to my class and everyone looks at her and say 'You didn't, did you?' She nodded with a grin on her face and the class went 'SHE GAVE BIRTH OMG' and a boy started to sing I wouldn't mind.
