In her night terror induced state, it was telling her that Dean wasn't Dean, but the wendigo coming back to get her which just made it all the worse as she desperately tried to break free from his grip from around her but she couldn't break free. She cried and cried out for Dean in her sleep until his voice started to break through her night terror. 

It started off an echo in the night terror, as if it was her mind trying to conjure him into the memory to save her, except it wasn't a dream version of him, it was him in the real world calling her. As he kept whispering and begging her to wake her, she eventually got shaken out of her night terror, opening her eyes quickly and gasping for breath as she tried to compute that it was just another night of reliving her trauma. 

As she looked at him, at first it was like she was looking through him before she finally managed to focus on Dean properly, breaking down completely and burying her face into his shoulder sobbing and shaking like a leaf. She never wanted him to witness the full extent of her night terror memory, she didn't want to dump it onto him like this, to her it wouldn't be fair to do such a thing. Yet her mind had very different plans it would seem. 

She held onto him for dear life as if he would be just ripped from her like her parents were, as she desperately tried to stop crying but the tears kept flowing anyway, her tears falling onto his shoulder. This was the truth of her trauma...the result of still not having not closure or knowing what the hell saved her that night. This was the scared Mika that was even more scared than when her father would punch her when she was a kid.

She just hoped she didn't wake Bobby from her screaming as she knew it always terrified him when the terrors got this bad for her. "I-I-I'm s-s-orry..." she sobbed onto Dean stammering her words.
