Not at all. Not only does Daenerys's fever dream in AGoT imply that she'll die while fleeing (having her back turned to the Others), Bran's vision is the one that made me see this. You already know that post I had with Drogon having a spear in his neck where Viserion died and another one in Drogon's back. There was a continuation error that made it seem like it was more than just an accident.

Anyways, getting to Bran's vision.

It goes from Catelyn having her throat cut, to a dragon (Viserion had his throat cut) to a Dragon flying over King's Landing to Daenerys and Drogon to the Night King turning the baby into a White Walker. In the next string of visions, it goes from the dragon again to the Mad King who had his back cut from Jaime, to the Night King raising wights, to the dragon again to Catelyn having her throat cut to the dragon over King's Landing to Daenerys and Drogon and the Night King turning the baby into a white walker.

If this doesn't convince you that Bran's visions foreshadow something, then look at the second part of the vision.

I've been saying Arya will use Jaime's face to kill Cersei. Widow's Wail is one of two swords from Ice, the thing I've been telling you is lightbringer, and the valonqar wrapping his hands around Cersei's throat is her becoming a captured lion. Widow's Wail will be shoved into Cersei's heart, and look at how the second part of the vision plays out:

It goes from Jaime to Ned asking "where is my sister" to Lyanna's bloody hand to the Mad King being slain the back to Robb being stabbed in the heart back to the Mad King being slain in the back. Jaime's sister is Cersei. Cersei is likened to the Mad King in the books and the community. It goes from Jaime slaying the Mad King to Robb being stabbed in the heart to the Mad King being slain again.
