Not really sure if i got the message for the dance this episode. But i guess it's supposed to look like a bridge that crosses over to death, and in that era where there isnt much visual symbolization of that it immediately connects the audience to that bridge and thoughts related to it. I wish they would show more about the dance like it previous episodes though, as this episode felt more like they wre just showing how people feel watching the dance, not how the dance looks like itself.
