It seems that you can withstand the pressure of work alone, because you will always try to do something that others take for granted. Although tired, I won't be bored. But your stress goes far beyond work. In life, some things are different from your thoughts, and you may feel wronged. For example, you want a free life, a romantic and beautiful love, respect from others, bossing around, and so on, but your cowardice makes you unable to escape the shackles of tradition, so you can only live a normal life (I feel that you may be a girlish, sentimental and courageous person). You live like this, but at the same time you hate your own way. You think you should make a breakthrough.
This is my interpretation of your dream.
Let's talk about the bomb shelter.
The bomb shelter is actually a very conservative but cold thing (think of dim lights and cold concrete walls, it is not difficult to understand), which is probably a feeling of the status quo in your heart. In such a space, you are at a loss, and you are asked to find your spiritual home in it. Think about it? Come on, you don't think it's realistic in your heart.
Suggestion: Go outdoors more and do more exercise. It's spring now. Let's put our work and life aside, find one or two companions, go out for a walk and get some fresh air. Good wishes!
