Why did I dream about my future daughter?

When I was 20, I had a dream where I was a mom. I always knew I wanted to be a mom but, I feel like before it was because that was what my brain understood as the "right" path of life (I don't think this way anymore). After that dream, something shifted, and being a mom became the desire of my heart. I think about that future every single day.

The dream was pretty simple, that was what made it interesting. I was at a restaurant and I had little girl in my lap. She couldn't have been more than 2 years old. We were sitting at a very small children's area with a few other random children, where a TV was playing some cartoon to keep the kids entertained while they waited, I guess. I was the only adult in that space. I remember she was really quiet and serious while the other children (a bit older than her) were so energetic. I just kept smiling while I held her because I felt so content just being there with her. I knew she was mine.

Fast forward to the next part of the dream: My entire family was at the restaurant, and we finally went to the table. She was sitting on my lap again, super attached. She never once spoke and she had a very introverted personality. All I felt was warmth. I felt so fulfilled. My uncle shouted a name across the table, and I don't know if it was for her... it's my older cousin's name and I don't believe I would've chosen it for a daughter of mine.

She looked exactly like I did at that age. She had my entire face. She wasn't as pale as I had been as a toddler and the color of her hair and eyes wasn't the exact same as mine, but she was my twin. And I could see myself, sitting at that table. I had long hair and I still remember the hairstyle. I looked more mature and slimmer (which I became a few years after the dream, since I had always been overweight).

This dream happened a few years ago but, and it hasn't come true (yet). I'm not one to give much attention to the meaning of the dreams I have (although I have an easy time remembering most), but this one always stuck out to me. It felt meaningful.

Did I meet my baby? Or am I giving meaning to a simple dream?
