Here We Are, All Dust, All Stars

My bed is very close to the roof and something is alive inside the roof, scratching at the metal terrifyingly close to my face. I was wondering what it would be like if the Earth became uninhabitable and humans had to board a giant ship out in space. What would I miss the most? I think I would miss the things that pictures could not capture-like the smell of nighttime through an open window, the hypnotizing quality of a fire, the tingling feeling when you get out of really cold water into warm air, or the plummeting weightlessness that comes when you're running down a sand dune.
