To dream of a friend represents a quality in yourself based on your most honest feelings about them. Ask yourself what memories or feelings stand out the most about them and see how that quality may apply to your own life.
Friends in dreams may also represent your current projection of that person based on a current situation or conflict in your life.
To dream of having a friend that you’ve never seen before represents beliefs or situations that make you feel good, or help you in some way. A supportive or co-operative aspect of yourself. It may also reflect your projection of a situation or arrangement that is beneficial to you.
To dream of a friend dying may represent your negative feelings about an impending change, loss, or failure. Consider what qualities stand out the most about that friend and how that quality may be lacking or suffering in your life at the moment. Alternatively, seeing a friend dying may reflect your feelings about that person losing power or undergoing an unpleasant change.
To dream of a deceased friend most likely reflects a quality about them that stands out the most in yourself. Unless their death was recent or you are having issues with grieving the fact that they are dead is most likely not significant to the dream symbolism. Alternatively, dreaming of a dead friend may represent something good in your life that has been long lost.
