Hell there. So I still don’t get the headache part, I mean in 138 she has them cuz of the dream/au etc but ever since she was a child, throughout the manga, only few chapters ago? Had she been seeing the dream for a while or just now?
Hi there🤠 Well...Regarding the headaches and their connection to seeing visions/au/dream, I think there are 2 explanations:
1. Headaches are the sign of her anxiety, which are caused by the traumatic experience she saw when she was a child. Her parents were murdered and Eren also killed 2 men in front of her. Isayama also draw these headaches differently from the vision/au/ones.
Two instances of her anxiety headaches are when Carla and Armin died. As we can see, Isayama didn’t draw some visions after that or it wasn’t as painful and severa as her vision/au/dream headaches.
Another example is when Eren said that titan shifters will die after 13 year time span after inheriting a titan.
Mikasa has a separation anxiety and she simply gets headaches when her trauma is triggered.
2. Another type is her vision/au/dream ones and here Isayama always puts a vision/au/dream after them.
Mikasa got a headache + vision/au/dream after talking to Louise. Remember, Eren also was in the prison at that moment and she has got them before Eren said that he hates her. Here, Eren wanted Mikasa to turn his back on him and forget (we all know this situation).
In ch.138 she got a headache + vision/au/dream again.
So, Mikasa has 2 type of headaches and no, her previous headaches were a symptom of her anxiety and trauma, while the most recent ones are because Eren (or Ymir) wants to manipulate her memory or use the power of Founding Titan. But because she is an Ackerman and they are immune to memory manipulation and the power of Founding Titan, she gets a headache and it’s way more painful that the regular ones.
