When I think about actually being in space I always imagine standing inside a space ship/station, putting my hand on the wall and knowing that like a meter or so away there's deadly, pitch black, unending abyss. Just a meter of relatively fragile material separating me from virtually infinite death. It just feels so antithetical to human life (at least on an instinctual level). It kinda makes me think of cosmic horror too (in the subdued way in which it was portrayed in a good chunk of Lovecraft's stories, not in the more visual and physical way it's usually shown nowadays).
