Dance with Death: Interpreting the symbolism of Arya and the pale horse

Lets consider the clues we’ve explored that suggest both Arya and the horse she discovers are already dead:

• Both Strickland’s steed and Arya have been felled. Arya rises from an unseen spot in the first shot of the sequence, which suggests she was originally down. The last time we saw her she was running from Drogon’s flames. If her lifeless body lay on the ground, we wouldn’t see it.
• Arya’s early camera shot that matches her swaying makes her seem as if she’s floating loose from the background, unattached from the real world.
• The scorched horse toy in the dead girl’s hand hints that Strickland’s horse is dead, and so is the person who finds it.
• We saw Strickland’s horse die (we think), so it might not be “alive” when it appears to Arya.
• Death brings Hades/Hell with it. Both Arya and the horse stand in the midst of a hellish landscape, albeit one created by Daenerys and Drogon.
• Both Arya and the horse she sees are covered in blood-streaked grey ash, suggesting a comparison to the pale horse and its pale rider (Death).

If we’re willing to run with this angle, then Arya has left the land of the living to enter the realm of the dead by mounting a dead pale horse. Therefore, Arya Stark is also dead. Arya and the horse are spirits. A living person looking down that street in that same moment would see nothing but dead bodies.

It’s not likely, but you can certainly interpret the sequence that way.
