If you dreamed of throwing a knife in your back: If you want to evaluate when you come across interesting opportunities, you should make a budget. There may be people who want to draw you into an environment of struggle, discussion or competition. Throwing a knife in your back in a dream means betrayal and disappointment from your loved ones, upsetting morale and being in trouble. Throwing a knife on one's back in a dream means solving the problems in the house, good events occurring, and everyone in the household being very attached to each other.
