Feels like something about the bystander effect, about feeling attacked or threatened while everyone around you is indifferent. And how in such a situation, you want more than just defence or neutralizing the threat, but some sorta vengeance? Ensuring that it won't become a problem again? Taking power/agency to do so, in a situation where noone else will?

This is just what kinda popped into my mind. Nightcap guru (from the other top post) suggested this:

> This dream likely symbolizes a feeling of helplessness and vulnerability in your current life.

> The indifferent people in the dream could represent a lack of support or understanding from those around you. The figure with the knife symbolizes someone or something that is causing you fear and anxiety. By taking the knife away from them and carving crosses onto their knees, you are asserting your power over the source of your fear and taking control of the situation. This dream could be interpreted as a sign that you have the strength and courage to overcome whatever is causing you fear and anxiety.
