My safe space was apparently 1950s America. Which is 20 years before I was born.
Funny you should say safe “space” instead of safe “place”. I conclude you must be a space alien of some kind. But, you know, I guess the 1950’s are my safe space, or place, since that decade comprises my earliest memories, me having been born in 1949, and many they are. These memories are definitely a “home base” to which one reflexively returns.
