How to Sleep in a Safe Space

I was really surprised about when I first went to Spain with my partner and spent time there with his family. People are just out here taking naps all the time like if they're home no matter who's at home as long as you're in the home, everyone's just asleep. Everyone is like falling asleep everywhere like in front of even people you've only met that day. To me that was really surprising because I feel like the rules around sleep and the norms around sleep are really different.
