Dream About Confusing Trains And Mysterious Strangers

This dream was about

Also before there was a dream about the train. I have been waiting for it on the platform with some other girls I knew. And then I went somewhere. To get water? After I was coming back, they were gone. I saw them on the other side. I thought that maybe we confused the trains. But my train came on the right platform, and they staid behind. I found a place on the train. Everything was so white and there were a lot of people and not a lot of space. But that's was okay. I took a coffee for myself and drank it from one swallow. Some people were staring at me. Especially that bold man in a black leather jacket. I have never seen him in my life or that I remember. There was a brochure. And on one of them were 2 Doctor Who. First David Tennant, that played 10th and 14th Doctor. And the other one was the new Doctor. Whose episode hasn't come out yet. I left the train. And if on the start it was sunny where I sat on the train, now it was really dark, but the snow was beautiful. I met my mom. We went to her friends house and then... And then I was on that platform again. I didn't understand what had been happening. And then, for some reasons I understood that I never went on that train. But how was this possible? I was staring on my phone while it was ringing (?) I think it was my mom. She asked where I was.
