Seeing a black king cobra in a dream often represents potential danger and threat. It could be a symbol of an impending confrontation or an indication of some unknown fear that you might be facing in waking life. The fact that the snake was in the living room of your home suggests that this concern or challenge might be related to your personal life or family.
The killing of something by the snake might represent the idea of destruction, and a friend taking the snake away could mean that help is on the way to deal with this threat. This dream could be a message that you need to be cautious and alert in regards to potential issues that you may face in the near future. It is important to be aware and prepared for any challenges or obstacles that may come your way.
