I had a twin sister. I wasn't born with her, but she was created spontaneously from a part of my soul, and I woke up one day to find us cuddled in bed. Despite that, she only looked the same as me, and she wasn't a copy of my personality. She took a few days to learn how to speak easily, and when she did she was more outgoing than me but she was also a bit brash and sometimes hurtful when she spoke without thinking. I remember her being much happier than I was, but I wasn't envious of that. I don't remember much of what happened in the dream but I think we were back at school, except the school was now the office I currently work in. We always had each other's backs, and together we made a lot of really good friends. I let her have the bigger bedroom in the house without hesitation, something I wouldn't do in real life, especially for one of my siblings. Despite that, I think she really wanted to share a bedroom with me anyway.
The dream may be related to your inner desires and wishes for a close relationship with someone who you can trust and rely on. The twin sister who was created spontaneously from a part of your soul could represent a part of yourself that you have overlooked or neglected. She may also represent your desire for a close, intimate, and meaningful relationship with someone who understands you deeply. The fact that you were at school, which was now the office you currently work in, could indicate a desire for something more fulfilling in your life. The dream may be highlighting the importance of friendship and companionship, and how it can make life more enjoyable and fulfilling. The fact that you let her have the bigger bedroom in the house without hesitation could also suggest that you are willing to make sacrifices for the people you care about. Overall, the dream may be a reflection of your need for a deeper connection with others in your life.
