Did Walt black out when he and Skyler has a fight?

At the beginning of the fight we see Skyler pull the knife from the kitchen and swing at Walt.

After a bit of wrestling and fighting Walt is on top of Skyler with the knife until Jr pulls him off and begins calling the Police.

On the phone call Jr states "He pulled a knife on my mum, he attacked her, he is dangerous etc", meanwhile Skyler has a terrified look on her face, she would be scared yes, but terrified when she was the one who started it?

Is it possible Walt blacked out and attacked Skyler and only came back to reality after Jr pulled him off Skyler?
