First of all, you said that the old man in the dream is a person with high status in reality. According to your description of the dream, lead it to the ladder, which is very high, as high as a mountain. I guess you may have more contact at work. Your dream of holding his hand and climbing the stairs implies that you are working hard together and hope to achieve more achievements in your career. In the dream, you feel that he has no strength later and his eyes are closed. This implies that in reality, you think that although the old man has a high position, his working ability is limited and what he can do is limited. So in your dream, you picked him up and climbed the stairs together, which symbolizes that in reality, although you think his ability is limited, he is still a powerful person, and you may still want to rely on him or make your career more and more successful with his help. You were careful along the way, and his eyes were closed, which also symbolized that he affirmed your help, or was willing to help you in your career. Another possibility is that your reaction to him in reality is a bit unpredictable when his eyes are closed.
The above is for reference only. I hope I can help you.
