Last September, NPR encouraged the public to ask questions of astronauts, then interviewed ESA and NASA astronauts using these questions. The full list of participants is impressive:

NASA astronauts Cady Coleman and Serena Auñón, European Space Agency astronaut Samantha Cristoforetti and NASA Chief Scientist Ellen Stofan came to NPR headquarters in Washington, D.C., Tuesday to talk with NPR's Adam Cole about space exploration, women in STEM, and common misconceptions. They also discussed what it was like to dream in space, the difficulties of coming back down to Earth, their favorite space movies and the most exciting planets in the solar system. Oh, and which foods they wished they had in space.

In the half-hour video below, NPR's Adam Cole runs through the questions. My favorite bit:

On dreaming in space

Cady Coleman: I definitely dreamed weightless. You'd be going somewhere in the space station, it was really natural. And then I would dream that way when I got home.

Wow. Okay, strap yourself in for half an hour of insight from astronauts (note that the video quality isn't great, but the audio is awesome):

If you prefer just the (typed-up) highlights, NPR has you covered.
