First of all, don't define it at will. That's not a soul, just an image in your dream. Many people will appear the image of the deceased within a period of time (usually January) after the death of their relatives and friends. This is mainly because the relationship with the other party has not been resolved or the desire has not been realized.
Secondly, I have never seen having sex with the deceased, which may have two meanings. First, you have a good impression on it, but you have never said it or made it clear; Second, the sexual behavior here has nothing to do with the death of the other party, that is, you are in a state of vain work mentioned in the synopsis of the golden chamber, so your dream is just superimposed with the dream of the deceased. Personally, I prefer to accept the latter. I want to know how you are.
Suggestion:
1. Dreams are the best way to communicate between Yin and Yang. If there is an unresolved relationship or desire with the other party, it can be realized in a dream, which is also the best self-psychological compensation mechanism.
2. Pay attention to whether you have kidney deficiency.
Wish you all the best!
