Did jon snow dream that he was Azor Ahai

[RamonTrujillo1]

I was reading a dance with dragons for the second time and I started to read jon snows second to last chapter for the book. It starts off with him dreaming that he was on top of the wall by himself defending an invasion from the others.

Here is a excerpt from the chapter:

“Jon was armored in black ice, but his blade burned red in his fist. As the dead men reached the top of the Wall he sent them down to die again. He slew a greybeard and a beardless boy, a giant, a gaunt man with filed teeth, a girl with thick red hair. Too late he recognized Ygritte. She was gone as quick as she’d appeared.”

Is his blade lightbringer?

Also, Mormonts crow wakes him up in the middle of his dream and says:

“King,” and, “Snow, Jon Snow, Jon Snow.” That was queer. The bird had never said his full name before, as best Jon could recall.

Is this bran trying to communicate with jon?

He calls him king. Does he know R+L=J already? Does he know jon is the rightful air to westeros?

You convinced me. Except for the part about Bran. Sub Bloodraven.

[Fire Eater]

Mormont's raven could be warged by BR who has seen the future.

You convinced me. Except for the part about Bran. Sub Bloodraven.

(That was weird.)

I don't remember this at all. I need to reread these books again.
