I dreamed that many people died when a tall building collapsed, and blood dripped on me.

Building a tall building means improving the present situation, or gaining a higher social status, or achieving a higher goal. Dreaming that everything has collapsed means that something has been destroyed, such as love, or something has happened that can subvert your existing values. Dreaming of being with a married woman: Do you know her? Your present situation, background and experience are the key to dream interpretation. This dream probably reflects your relationship with this person, or reflects immoral behavior or thoughts. I dreamed that her husband found out, then I got into a fight with him, and finally I sha: fighting is a kind of conflict, which is a kind of competition. Sha stands for ending and destroying competitors. Similarly, your experience is the key to dream interpretation. Good luck!
