Journeys through Spacetime

I have a mundane dream about life...
However, my dream is repetitively haunted by people asking me what 1% of 5 is. I cannot answer.

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.
