1. Dreaming of a deceased long-time friend is usually a continuation of emotions, which may indicate that you still miss this friend deep down, or that some of his influence in your life still exists.
2. This kind of dream may also be a subconscious helping you deal with unfinished emotions or affairs, reminding you to cherish the person in front of you and let go of certain past obsessions.
3. There is no absolute good or bad in dreams themselves, the key lies in how you interpret and respond to the emotions and inspirations they bring. If you feel comforted or inspired, then this is a positive dream experience.
