Dream 20.3. On the Rails

It started with me standing on a railroadstation with my grandma. She said something silly/weird and I boarded the train.
The different sections of the train were playing different movies on huge screens. I sit on a plce which is playing somekind of a documentary. Suddenly I notice that there are no chairs anymore and everybody is just laying on the floor.
The theme of the carriage changed to different candy manufactorers and everyone got a free bag of candy.
The train arrived to the main station at capital city that had a warped appearance, yet similar from some of my other dreams.
A woman in her 30's called saying "You're too good for that". She ended the call and the dream offering me sex.
