Dreams can often be a reflection of our thoughts, emotions, and relationships in waking life. In your dream, visiting Ruben and their partner's apartment might symbolize a desire for connection, comfort, or exploration of your relationships. The presence of David checking up on you could indicate that you value his support or care in your life.

The act of being shown around the bedroom suggests intimacy or a deeper understanding of your feelings or those of others. Laying in bed can represent vulnerability and trust, suggesting that you feel safe in this space.

The brunette Blythe Doll could symbolize childhood memories or aspects of femininity, creativity, and playfulness. However, when it turned into your eldest sister’s head, it may signify unresolved feelings or fears related to your sister. This transformation could represent a fear of losing innocence or a sense of horror about changes in familial relationships.

Overall, this dream might be prompting you to explore your feelings about your family dynamics, intimacy, and the nature of your relationships. Consider reflecting on your current feelings towards your sister and how they may be influencing your emotional landscape.
