I read this story/novella at least 15 years ago, probably 20 or more.
It is about a ship, travelling through the universe, looking for habitable planets. Why, I can't remember. People are held in Cryo Stasis and I think they are wearing nothing in the chamber but some kind of mesh. Every time the ship gets close to a planet it wakes one or two of the people (one woman, one man?) to check it out but they never find anything good.
I think in the end they wake up and discover, that they have arrived back at Earth.
Other details are very vague but I seem to recall there was lots of stuff about a (blue?9 light, dreaming/dreams and something about the cold, or cold blue lights or similar.
Does that ring a bell for anyone? Details might not be 100% accurate so please also offer your best guess if you know something similar.
