To dream of yourself at the wake for a waking life friend or family member foreshadows the telling of sad or disastrous news.
To view a friend attending a wake is far more ominous, as it indicates that the friend may be in mortal danger.
Waking up in a dream is an indication that you are unhappy in your life. There is a missing or incomplete aspect. Consider your life, what goals have you not achieved? What is missing? Use your talents or abilities to obtain them.
