Thank you for the trust you had to share your dream. You talk about your "almost something", and dreaming about it is not trivial. We explain everything to you.
To begin with, the first scene of the dream takes place at school. Dreaming about school has a rather regressive dimension, whether you are still there or not. In one way or another, it relates to an event that is currently happening in your life.
Dreaming about your crush does not lead directly back to it. It only does when it haunts your thoughts.
You think about him all day long and at night, all this resurfaces in the form of a dream. This is the classic explanation. These are buried desires that resurface.
On the other hand, if you don't think about it that much, we turn to another alternative. In fact, dreaming about someone you like appeals to your sense of action.
Your inner part that is in charge of the word is calling you to action, that's what it's all about. You need to make up your mind to take action (in work, in your personal life, whatever).
As for the kisses with this same person, they express harmony. But behind these scenes are hidden in reality a malaise, a desire for emancipation. You want to blossom and reach happiness.
The scene of the rain and the feeling of confusion confirm this theory. You have an interior malaise.
But the good news is the meaning of this rain. It symbolizes positivity, fertility, a kind of emotional cleansing.
So you can be sure that you will get past this inner discomfort and come into bloom for your fulfillment.
