Duncan looked like Lady Macbeth's father.

Explanation:

According to Lady Macbeth, Duncan looked like her own father. For instance, in the play, she says, "Had he not resembled / My father as he slept, I had done't" (2.2.16-17). Thus, she didn't want to kill Duncan because killing him would seem as if she killed her own father and that decision would give her nightmares.
