(Spoilers everything) Noticed some similarities in the poem the composition "Danse Macabre" is based off of.

So, this will all fall under conspiracy, thin contrived lines area of discussion, but I thought I'd share anyways.

You've probably heard the Danse Macabre at some point; just look it up and you'll recognize it. It's about the undead rising on a full moon, partying and dancing the night away. It's also based off an old poem, which I'll post here:

"Zig, zig, zig, Death in cadence, Striking a tomb with his heel, Death at midnight plays a dance-tune, Zig, zig, zag, on his violin.

The winter wind blows, and the night is dark; Moans are heard in the linden trees. White skeletons pass through the gloom, Running and leaping in their shrouds.

Zig, zig, zig, each one is frisking, You can hear the cracking of the bones of the dancers. A lustful couple sits on the moss So as to taste long lost delights.

Zig zig, zig, Death continues The unending scraping on his instrument. A veil has fallen! The dancer is naked. Her partner grasps her amorously.

The lady, it's said, is a marchioness or baroness And her green gallant, a poor cartwright. Horror! Look how she gives herself to him, Like the rustic was a baron.

Zig, zig, zig. What a saraband! They all hold hands and dance in circles. Zig, zig, zag. You can see in the crowd The king dancing among the peasants.   But hist! All of a sudden, they leave the dance, They push forward, they fly; the cock has crowed. Oh what a beautiful night for the poor world! Long live death and equality! "

I think it's pretty interesting the lines that can be drawn.

1. The winter winds

2. Night is dark

3. Moaning linden trees(which, by the way, do share a lot of physical similarities to the tv shows weirwood trees)

4. The undead skeletons rising clearly connected to the white walkers.

5. The baroness and the cartwright(nothing confirmed, but could be represented through the chance of Jon Snow and Dany getting together)

So yeah, not a lot, but still neat, and thought I'd share.
