Dreams involving violence, loss, and sacrifice can often reflect internal struggles or feelings of vulnerability. In your dream, being pulled during a fight suggests that you may be feeling overwhelmed by a situation in your waking life, possibly related to a relationship or a conflict. The act of cutting off your right arm symbolizes a significant sacrifice or a drastic measure you might feel you need to take to protect someone or something important to you.

Your choice to leave the other person behind could indicate feelings of guilt or conflict about prioritizing your own needs over someone else's. It may also reflect a sense of helplessness in the face of a situation where you feel you cannot save everyone, leading you to make difficult decisions.

The indifference of those around you after losing an arm might suggest feelings of isolation or being unrecognized in your struggles. It could reflect a fear of not being valued or understood by others despite your sacrifices.

Consider reflecting on any current situations in your life where you feel the need to protect someone or where you might be making significant sacrifices. This dream could be urging you to acknowledge your feelings and perhaps seek support from those around you. It's important to ensure that your own well-being is also a priority.
