With Dawn showing up and she writing using the symbols, I'm beginning to think that maybe instead of being trapped in the speed force all that time, that maybe Barry spend some time in the future.Its where he picked up the symbol (which could be future writing) and details of his past. In the comics, after he died fighting the anti-monitor, he put off his death for a while so he could travel to the future to have children with Iris before returning to finish off his death, so maybe we're getting a storyline inspired by that...I doubt it but its fun to spitball random fan theories!
