Experiencing some developments that will cause regret means that the person constantly blames himself for this and, so to speak, eats himself up. It means the realization of a humane event that will always be remembered as a mistake but can happen to any human being. Killing a man and escaping from prison in a dream indicates that you will be in great anxiety and uneasiness about something. It signifies an issue that the dreamer is afraid of being revealed and heard, and that this issue is gnawing at his brain.
