Multiple characters in the story have prophetic dreams about the Red Wedding. Theon, The Ghost Of High Heart, Patchface, etc. But the prophetic dreams are too weird and hard to interpret for the person who’s having those dreans. I could only imagine what it would’ve been like as a book reader back in 2000 when A Storm Of Swords dropped and you’re reading about the Red Wedding in real time, and then you go back and realize all those dreams that such n such character had, was about the Red Wedding!!!! Theon: Theon has a dream about a feast with all the dead ppl. Ned Stark is there with no head. Lyanna Stark is there wearing a blood soaked dress. King Robert is there with his guts spilling over the table. And then the door flies open, and a man with a wolfs head walks in with blood all over his clothes. If you remember, after the red wedding the Frey’s cut robs head off and sew his direwolfs head to Robs body. The Ghost Of High Heart: When Arya is traveling with the Brotherhood Without Banners they meet this prophecy telling Woods Witch called “The Ghost Of High Heart”(not an actual ghost, but she’s a witch). And she tells them of a prophetic vision she has of a howling wolf crying in the rain, and no one is there the help him. And before that, she talks about a vision she had of a ladies body in the river floating down stream, and this lady is dead as hell. But then her eyes open and it’s the scariest vision The Ghost Of HighHeart has ever seen. The ghost of high hearts first vision describes Rob at the Red Wedding, or Robs Direwolf being killed at the Red Wedding. And her 2nd vision describes Catelyn Starks dead body being dragged from the river and Catelyn being raised from the dead by Lord Beric Dondarion, and Catelyn thus becoming the undead Lady Stoneheart, beginning her arc as a vengeful undead merciless woman who roams the riverlands getting vengeance on the Lannister’s and Frey’s. What’s a trip is, Arya unknowingly drags her mom’s body from the river when she’s warging(skinchanging like Bran) as a wolf. Arya just thinks she’s having a dream. Patchface: Patchface speaks in meaningless rhymes and riddles, but some of his riddles are prophetic visions. Patchface in the 2nd Book(A Clash Of Kings) sings: Fools Blood, Kings Blood, Blood on The Maidens Thigh, but chains for the guest and chains for the bridegroom Aye, Aye, Aye!! The Fools blood is that of Aegon Freys(the fool of House Frey who Catelyn kills after they’ve killed rob. The kings bloods is obviously Robs blood. The blood on the maidens thigh is from Roselyn Fray losing her virginity to Edmure Tully at their wedding. And the chains for the guest and bridegroom represent the chains of all those the Northmen and Tully loyalist taken hostage, including Edmure. So if you’re reading the book in real time back in like 2000, I bet folks were like How could I have missed that!!! That’s what that vision meant!!!
