To dream that you kill someone means that you may be feeling very stressed lately, and sometimes may lose your self-control. It’s interesting to remember whom have you killed and how do you feel about that person. Do you feel angry for some reason towards that person and didn’t realize it until now? Sometimes we do things that annoy others, but it’s difficult for us to recognize our anger and our pain. On the contrary, a dream in which you kill a person can represent a part of you that you may dislike and want to get rid of it.
