Who could Arya be running from in the season 8 trailer?

Potential Spoilers Below

Could Arya have been afraid and running from Bran?  She was in the crypts and in the dark?  Could she have gone deep into the crypts and run upon Bran enshrined in the Winterfell weirwood?  Could that have actually scared her though?  It did Jon as Ghost in a wolf dream of sorts as what he found was Death.  Bran asked Jon not to be afraid of him.

Arya from the trailer: I know Death. He's got many faces. I look forward to seeing this one.

Excerpt from A Clash of Kings:

Jon?

The call came from behind him, softer than a whisper, but strong too. Can a shout be silent? He turned his head, searching for his brother, for a glimpse of a lean grey shape moving beneath the trees, but there was nothing, only . . .

A weirwood.

It seemed to sprout from solid rock, its pale roots twisting up from a myriad of fissures and hairline cracks. The tree was slender compared to other weirwoods he had seen, no more than a sapling, yet it was growing as he watched, its limbs thickening as they reached for the sky. Wary, he circled the smooth white trunk until he came to the face. Red eyes looked at him. Fierce eyes they were, yet glad to see him. The weirwood had his brother’s face. Had his brother always had three eyes?

Not always, came the silent shout. Not before the crow.

“He sniffed at the bark, smelled wolf and tree and boy, but behind that there were other scents, the rich brown smell of warm earth and the hard grey smell of stone and something else, something terrible. Death, he knew. He was smelling death. He cringed back, his hair bristling, and bared his fangs.”

“Don’t be afraid, I like it in the dark. No one can see you, but you can see them. But first you have to open your eyes. See? Like this. And the tree reached down and touched him.”

Comments encouraged.  Love to hear the idea’s of others.  Most believe that since I present my idea’s as “fact like” I’m not open to change my viewpoints which is far from the truth.  I simply look at the information presented and go from there.  If you can shine a light on another way of thinking that opens the door to debate.
