Dreams like yours can be quite vivid and emotionally charged, often reflecting your subconscious thoughts and feelings. Here are some possible interpretations of the different elements in your dream:

1. Waking Up Alone: This may symbolize feelings of loneliness or a fear of losing your partner. It could also represent a desire for more independence or a need to address something in your relationship.
2. Partner’s Condition: Your partner being "very purple" could symbolize feelings of distress or concern about their well-being, either physically or emotionally. It may reflect anxieties about health or changes in your relationship dynamic.
3. Calling for Help: This aspect may indicate that you feel helpless or that you want to be a supportive partner but fear that you can't always help in difficult situations.
4. Funeral Scene: Funerals often represent endings or significant changes. This could symbolize the fear of losing something important in your life or the end of a phase in your relationship.
5. The Stranger: The appearance of someone who resembles your partner but with different features might suggest a longing for new experiences or a different aspect of your partner's personality. It could also reflect a desire for emotional or physical intimacy after facing grief.
6. Emotional Comfort: Feeling comfortable with the stranger may indicate your need for emotional support and connection, especially during difficult times. It might symbolize your subconscious desire to explore new dynamics in your relationships or aspects of yourself.

Overall, this dream could reflect underlying emotions relating to your relationship, changes you may be experiencing, or fears you may have. It might be beneficial to discuss your feelings with your partner or reflect on what you truly desire in your relationship moving forward. Consider what aspects of your life you want to nurture and explore.
