Grandfather's dream is the most representative. It can be seen that in the family relationship, your childhood and grandpa may not have a good time, so he died in the country (your grandmother died in your room). There is a third person here, the driver. This should be another symbol of your personality. It can be seen that in real life, you used to haggle with your family for some trivial things, and then you reflected on it yourself, but you never had a chance to explain it to your family. In real life, parents and grandparents are never very close, so your reflection in your heart is that none of your family was present at the memorial service. You may have been sorry for your grandfather because of your childhood, so you will see the release of the memorial service on TV. Television is the embodiment of self-awareness here, which shows that you still attach more importance to your grandfather. Then this dream should be the overall expression of the contradiction between the real life situation and the inner hope from beginning to end, which shows that you are not very suitable for the job at hand now and very much hope to have time to relax with your family. At the same time, we can see that your family education is very strict, and you have been in contact with your grandparents for a long time in your childhood. As the eldest son or only son, you may have a certain burden at home.
I don't have to consider the objective conditions you gave me. In fact, to put it bluntly, dreams are a direct reflection of your own subconscious. As far as your dreams are concerned, let me tell you what your subconscious is like.
First, several fragments of the dream are almost all related to the death of relatives, and they are all your most immediate relatives. Therefore, in your essential consciousness, you are the last person to lose them. You will feel sad because if you lose them, you will feel helpless and afraid. So this kind of emotional venting will be manifested in a very sentimental dream.
Second, you didn't actually see (her) body in your dream, which is a contrast of not wanting or being afraid of losing the feelings of grandma, grandpa and mom in reality.
Third, dreaming about the birth of a child just means that you don't accept the emergence of new problems and new situations, that is, you have to be content with the present situation in reality (or maybe repair the tombstone for grandparents).
Conclusion: You have deep feelings for grandma, grandpa and mom. Maybe you grew up under their care, so your feelings can only be them. As a young man who has just worked for a year, his work is definitely not very smooth, and he may even suffer some setbacks and difficulties. Understandable, but on the other hand, his dream can reflect your lack of friends who give you spiritual comfort, encouragement and support.
Suggestion: Make more friends and comfort each other spiritually with relatives.
