Waking up in your room as a ball of light could symbolize a transition to the afterlife or a spiritual awakening. Seeing other dead people, some of whom are ‘bad,’ could represent your own inner demons or negative aspects of your personality that have died. The one person who informs you of your death could represent your subconscious trying to make sense of the situation. Watching over your mom as a guardian angel could symbolize your desire to protect and care for your loved ones even after death. This dream may also suggest a need for closure or resolution in a past relationship or situation. It could also be a reminder to cherish and appreciate the people in your life while you still can. Overall, this dream may be a reflection of your thoughts and feelings about death and the afterlife, and your desire to find peace and purpose in the unknown.
