Obviously we know that Xander was afraid of his marriage turning out like his parents'. But I was thinking that vision of him hitting Anya might have scared him more. It would terrify him to think that he might have that kind of violence in him, and that he might do something to physically hurt Anya. Kind of in the same vein as when Wes (after contact w/ Billy) was ashamed of himself for attacking Fred. Both are inherently "good" guys who would never hurt anyone, but would be very afraid and confused if somehow presented (via demon-vision, or demon-infection) with the idea that they do have a capacity for violence towards people they care about.
Just some ramblings before bedtime.
