I'm deeply sorry for your loss. Dreams can be a powerful way for our minds to process grief and emotions. In your dream, several themes emerge that may reflect your current feelings and experiences.

1. Breakup and Concerns about Success: The scenario where your partner wants to break up due to concerns about you being successful may symbolize your fears about moving forward in life without him. His belief that he might hold you back could reflect your own worries about the future and how to navigate it without his support. Your insistence that you could be successful together suggests a desire to maintain your bond and not let go of the past.
2. Emotional Expression: Your declaration of feeling suicidal without him signifies the depth of your grief and the emotional turmoil you are experiencing. It shows the strong connection you had and how much you relied on him for emotional support.
3. Nostalgia and Creativity: The conversation about Michael Jackson's "Thriller" album may represent a longing for joyful memories and creativity from the past. This part of the dream might be a way for your subconscious to remind you of the good times you shared and the aspects of life that brought you happiness.
4. Friendship and Comfort: Transitioning to your friend's house, where there is a baby, symbolizes new beginnings and the potential for nurturing relationships. The baby can represent hope, innocence, and the possibility of new life or experiences. Sharing a bed with your friend might indicate a need for comfort and support during this challenging time.

Overall, your dream reflects your grief, the struggle between moving forward and holding onto your past, and the need for comfort and connection with others. It might be helpful to talk about these feelings with a trusted friend or a professional who can support you through this process. Remember that it's okay to seek help during such a difficult time.
