Journeys through Spacetime

I am on a train through the Arctic. At some point the driver tries to crash the train, but fails. I spend some time at the pole, and I am offered a last tour. I refuse, but I quickly regret that.

I was on a train, and the train doors randomly opened and closed. I lost valuables. M is causing it.

I am on a street. It is dark. There are only black crows. I realise the sun and planets had been banished. They discover I am on the planet's side and I am thrown into a dungeon with them. The sun tells me he was discovered as a 'planet' during a solar eclipse.

I thought I might post an old dream I just remembered.
I am on a train to the South Pole. Lots of people I know are there. I feel this happy feeling of independence, freedom, and euphoria put together. It is so wonderful I cannot describe it anymore. It only appears in dreams. Eventually we reach a city at the South Pole. I have a best friend in the dream who is always with me. A wizard trains me spells and I remark 'This is like a lucid dream but real' to myself. Soon an earthquake happens and people are jumping off balconies due to fires and dying. I do what I can but I must leave. My companion, the wizard and I do lots of quests, but eventually my friend is killed. I feel horrible. I wake up.

I have to search for certain artifacts in a fantasy world. Eventually I have to get an artifact by going through a giant spider web guarded by a white spider. I run away from it so much that the dream loses its plot and turns in to a dream about getting on trams and trains.

I am sitting on a train, and I remember this is after some sort of war. The train is taking one of the old tracks not normally used for security.
