I dreamed that the suture wound on my son's arm was cracked and swollen without bleeding. I knelt down and begged for a dream.

Indeed, this wound can be understood as your son's recruitment will not be very successful, because the wound is very small, so it will not have much impact.

PS: You don't have to worry about that. Everyone has wounds. Why do you dream like this? Because you pay too much attention to this wound, your brain is always worried that the wound will crack and its deep memory system will record it. It will be released again when you sleep, just like it is true! But you don't have to worry. Dreams are dreams after all. You don't have to worry too much, do you?
