Dreaming about the death of a loved one, especially a parent, can be incredibly distressing and often reflects deep emotional processes. In your case, dreaming about your mother’s sudden death twice may signify unresolved feelings or fears related to loss, change, or vulnerability.

These dreams can evoke real pain because they tap into your subconscious worries about losing someone you love or facing significant changes in your life. Such dreams might also be a way for your mind to process grief or anxiety, particularly if you've experienced loss before or if there are stressful situations in your life currently.

Consider reflecting on your feelings surrounding your mother and any current life changes or stresses that may be amplifying these emotions. It might also be helpful to talk to someone about your feelings or to express them through writing or art. This can provide some relief and may help you work through the emotions tied to these dreams.
