What is the meaning in a dream of beach

Finding gold coins in the beach sand water

Well in the beggining, I was in the top of balcony near coast completly alone, so I went down the cobblestone steps surrounded by beautiful summer houses full of plants, until I got all the way down to the beach. Then I emerged on a wide promenade along the very edge of the beautiful sea. The promenade was more or less deserted, but I noticed some groups of young people talking to each other and I suddenly felt sad because I remembered that I was alone. Until suddenly, out of nowhere, a beautiful blonde girl approached me with the friendly intention of hanging out. Suddenly I didn't feel so alone and I was happy. We had a little walk, talking a bit with each other. I didn't even manage to ask her name. Then I woke up and felt a kind of sadness. That's my whole dream in a nutshell. Even I managed to notice a lot of symbolism in this dream. So hope you can help me even more to understand the meaning of my dream. Thank you.

I had a dream that all I remember were the colors in it. I was wearing a dress that blended in with the colors and all I could really see were my feet dancing in the sand. I could feel the sand. Layered from bottom to the top was beautiful a sandy tan brown color, a barely light pink color and extremely light blue. They were so beautiful and I had the best peace of mind and contentment I'd ever had before. I was happy with everything in my life. I could also feel warmth but cool comfortable warmth. My dress which blended me in with the environment surrounding me was ankle length airy with spaghetti straps; very casual beach like. I woke up with the best feeling and state of mind I have ever had in my entire life.
