Psychologically speaking, dreams are a reflection of the subconscious mind. This shows that although you are single in real life, you are very eager to have a satisfactory boyfriend. There is no doubt about it. You said you proposed when you went up the mountain, which is a good proof.
Besides, your ideal partner should be a handsome person, so although his image is vague in your dreams, you will remember that he is handsome, which is actually one of the conditions for you to choose a spouse.
Interpretation of dreams: Everything is actually your inner hope, but maybe you may have a peach blossom in the near future, haha.
Finally, I wish your dream come true.
