To dream that you attend a wake refers to your grieving process. You need to find closure. It is okay to seek the support in order to help you get through a difficult time. Alternatively, the dream suggests that it is time to celebrate the positive qualities of someone who is no longer in your life. 

To dream that you are waking up in your dream indicates that something is missing or lacking in your life. There is an aspect of your life that you are not utilizing to its fullest potential. You are not recognizing your abilities. The dream is literally telling you to open your eyes and wake up! Alternatively, waking up in your dream may be a signal of a lucid dream.
