Recent dreams containing promenade

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.
