In Handmaid's Tale, What can you tell about the period just from the first sentence?

"We slept in what had once been the gymnasium?"

What I put was that it was from long time ago because a gymnasium is used for playing sports, not to sleep and in this sentence it's telling us that they slept there.

So ... why would they be sleeping where people usually play sports??
They could be sleeping in a gym because of natural disasters (weather, etc).hope this helps
