Could this be a sign from Allah?

Salam Alaikum, I’m a 22-year-old woman and I’ve been thinking a lot about marriage lately and making small duas. A few nights ago I had a very vivid dream about a guy I don’t really know. In the dream I found out he was going to marry my female cousin and I felt really hurt because I wanted to marry him. That dream affected me emotionally and I kept thinking about it all day. The more I thought, the more I realized that in most of my marriage-related dreams he appears - once I even dreamt we were married, and it felt very real. I honestly don’t understand why my mind keeps bringing him up. In real life I don’t have any connection with him - I wouldn’t call it a crush, I just don’t know him. He’s the son of a family friend; our families have known each other for over 30 years. We’re not very close but we keep in touch. I haven’t seen him in person for over five years. I follow him on social media but neither of us posts much, so he doesn’t come to mind often. We invited his family to dinner last month since we moved closer, but they couldn’t come because of prior plans. Now that I really want to get married and I’m making dua, I’m wondering if these dreams are a sign from Allah - is this my naseeb? Should I ask my mother to invite them again? Should I tell my mother how I feel? Or try to start a respectful conversation with him, perhaps with a chaperone or through family? I’m also worried about community perceptions - I don’t want people thinking I’m the kind of girl who talks to boys casually. I’m honestly confused and don’t know what to think. Any advice on how to make dua, seek guidance, or practical steps I can take while keeping things within Islamic etiquette would be really appreciated.
