Hall of Infinite Doors

It's all black for a while. Then you open your eyes. The sight is simply breathtaking. You are in space, with hundreds, thousands and millions of stars around you. They blink and flicker, as trying to convoy you a message. There is nothing better than seeing your home galaxy, with all these stars only around you, greeting. But now, you realise something.

How are you not suffocating in space? Why it's not cold here? Why doesn't your head inflate? You're not exactly sure, but some unknown force is protecting you from the vacuum. You spin around, and then see the North Star. Now, you're sure where to go.
