Dreaming of an old man walking in the park with crutches?

I dreamed that an old man was walking in the park with crutches. This is a strange dream. Because sometimes I dream about old people. Your heart will grow old. But old people also symbolize good luck. I may think of it in my dream. I won't get old. But people get old. It is human nature to be old. So ... I dreamed of the old man. It will grow old in the future.
