I'm haunted by the image of him lying down to sleep on a tiny patch of ground barely the size of his body, surrounded by water. Like something you'd do in a dream.

I did my best with Solaris a few years ago, but it turned into an endurance test. I think I actually fell asleep at some point. I brought some strong dark chocolate to Stalker expecting to need to wake myself up with little caffeine bombs, but no, it was a joy.
