It Does Not mean a real physical death, the death is a change of the ways and even ideals of what you are and think now. It may be telling you that a change is needed in lifestyle, a change of friends or job or location. It may be one needs to move on to take a new and better path.
It means that there is some aspect of yourself that you don't like and want to change. Dreams typically exaggerate everything, so that an ordinary problem is visualized as a huge crisis. Because this question is posted on the day before Easter, on the morning after Good Friday (commemorating the sacrificial death of Jesus Christ) this dream could have a religious link, referring to the need to "die to sin" or "put to death this body of sin" in order to live in the righteousness of Christ. Such expressions speak of spiritual realities, not physical suicide.
I suspect you are under stress and working out a problem in your life.
This dream suggests that you are carrying a burden of guilt. You are blaming yourself but you cannot figure out a way to relieve that guilt without putting yourself in a worse situation.
This dream expresses your dissatisfaction with some aspect of yourself or with some part of your life. For examply, you might want to "kill the habit" of smoking, or eliminate your quick temper, or to stop giving in to temptation. In the exaggeration of dreaming, the need to get rid of something is expressed as "killing." By imagining yourself as a separate being, the dream allows you to separate one part of yourself from the parts of yourself you dislike.
When you dream about yourself flying, it only means that you enjoyed your daytime.

It means that the mud indicates dirty things. You dream yourself with mud. This means that you imagine yourself with dirty things.
It means that you have been the victim of emotional abuse. You need to find a wise (adult) person whom you trust, and tell them about these dreams.
It probably means that you are angry with yourself. The cousins in the dream symbolize the various aspects of yourself, and the many ways that you are too critical of yourself.
Of course, you Can't EVER kill an immortal being. In a dream, you can only End the dream itself. The most easy way to end a dream is to pinch yourself in the dream. Or you can continue the dream.
I assume you mean Suicide, and that's when you kill yourself.
