I don’t particularly like the Jojen Paste theory either, no worries. And no, I don’t think there’s any kind of power transfer via cannibalism. Varamyr ate Haggon’s heart while skinchanged into a wolf, not as a human being.

Had he sunk so low as to hunger after human meat? He could almost hear Haggon growling at him. “Men may eat the flesh of beasts and beasts the flesh of men, but the man who eats the flesh of man is an abomination.”

Abomination. That had always been Haggon’s favorite word. Abomination, abomination, abomination. To eat of human meat was abomination, to mate as wolf with wolf was abomination, and to seize the body of another man was the worst abomination of all. Haggon was weak, afraid of his own power. He died weeping and alone when I ripped his second life from him. Varamyr had devoured his heart himself. He taught me much and more, and the last thing I learned from him was the taste of human flesh.

That was as a wolf, though. He had never eaten the meat of men with human teeth.

–ADWD, Prologue

Many of Jon’s dreams do appear to be prophetic, yes. He has a reoccurring nightmare of returning to an empty Winterfell and being drawn into the crypts (where his mother is, though he doesn’t know that), which is certainly meaningful. Also, Jon dreamed of Winterfell’s burning before or possibly while it was happening. (That chapter is after Theon’s last, but the fan-made calendar has it before, I’m not sure what their reasoning is though.) And Jon dreamed of Bran as a three-eyed weirwood, which is also certainly prophetic, though that was also a wolf dream at the same time (more on that in a bit).

And then there was this nightmare:

That night he dreamt of wildlings howling from the woods, advancing to the moan of warhorns and the roll of drums. Boom DOOM boom DOOM boom DOOM came the sound, a thousand hearts with a single beat. Some had spears and some had bows and some had axes. Others rode on chariots made of bones, drawn by teams of dogs as big as ponies. Giants lumbered amongst them, forty feet tall, with mauls the size of oak trees.“Stand fast,” Jon Snow called. “Throw them back.” He stood atop the Wall, alone. “Flame,” he cried, “feed them flame,” but there was no one to pay heed.They are all gone. They have abandoned me.Burning shafts hissed upward, trailing tongues of fire. Scarecrow brothers tumbled down, black cloaks ablaze. “Snow,” an eagle cried, as foemen scuttled up the ice like spiders. 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.The world dissolved into a red mist. Jon stabbed and slashed and cut. He hacked down Donal Noye and gutted Deaf Dick Follard. Qhorin Halfhand stumbled to his knees, trying in vain to staunch the flow of blood from his neck. “I am the Lord of Winterfell,” Jon screamed. It was Robb before him now, his hair wet with melting snow. Longclaw took his head off. Then a gnarled hand seized Jon roughly by the shoulder. He whirled……and woke with a raven pecking at his chest. “Snow,” the bird cried.

–ADWD, Jon XII

This dream starts out as a memory of the battle at Castle Black, but soon becomes something else. It’s not important who Jon kills in this nightmare – though most reflect his guilt for the people he did kill (like Qhorin) or might as well have killed (Ygritte) or the ones he feels he failed (like Donal Noye), and Robb is a reflection of the memory of their youthful play-battles – but the fact that Jon’s killing people who are already dead is a sign of his future war against the Others and their wights. “Foemen scuttling up the ice like spiders” is, well, the Others will have ice spiders too. Jon’s dream here is an overt parallel to Dany’s dream of the Trident, where she thinks she’s fighting Robert’s men but they truly represent the Others.

But most importantly and symbolically, Jon was armored in black ice, bearing a burning sword. Jon will have the true Lightbringer one day soon. And as for the armor:

Euron Crow’s-Eye stood upon the deck of Silence, clad in a suit of black scale armor like nothing Aeron had ever seen before. Dark as smoke it was, but Euron wore it as easily as if it was the thinnest silk. The scales were edged in red gold, and gleamed and shimmered when they moved. Patterns could be seen within the metal, whorls and glyphs and arcane symbols folded into the steel.Valyrian steel, the Damphair knew. His armor is Valyrian steel.

–TWOW, The Forsaken

After Euron is cast down, his Valyrian steel armor will still be very useful. Who better to have it than Jon?

Now, regarding the nature of Jon’s prophetic dreams, his heritage provides him with two sources of “power”. #1, his Stark side, gives him wolf dreams through Ghost, which I don’t think are greendreams as such but could be related. (Since normally a wolf dream just lets him see what Ghost is doing and feel what the wolf feels, but in the dream of the weirwood-Bran, either Ghost was dreaming too or Jon’s “dream self” was a wolf, since the actual Ghost was in the mountains over the wildling camp, not in a forest with the tree.) They say only one skinchanger in a thousand is a greenseer, and the skinchanger/greenseer in the Stark family is Bran for sure. Could there be more than one? Maybe, but the odds are against it. Especially because when it comes to prophecy, Jon also has #2, his Targaryen side, and “there have always been Targaryens who dreamed of things to come”. Jon’s dreams aren’t as frequent or dragon-filled as Dany’s, but that may change.

Because yes, I do think Jon’s resurrection may change the nature of his dreams. As you said, a period of illness/unconsciousness seems to bring out those prophetic powers (Dany’s own were very intense in her fever dream), and, well, Jon’s dead, you can’t get more unconscious than that. ;)  (His mind will probably be in Ghost’s though, not sure if that will do anything to make a difference?) But if Jon is resurrected with fire, fire and blood… perhaps his Targaryen side may wake up stronger, and the dragon dreams as well.
