In my dream my cousin was smoking a cigarette first time but he was a twelve years old
Dreams involving smoking can often be symbolic of emotions, desires, or habits that you need to either embrace or let go of. The fact that your cousin, who is twelve years old in the dream, is smoking for the first time generally suggests that there may be elements of immaturity or childish behavior in your waking life that you need to address.
It is possible that this dream is highlighting an aspect of your cousin's character or behavior that you are observing as being inconsistent with their actual age or level of maturity. This could also represent a concern or worry about their well-being, especially if you feel that they may be engaging in more grown-up or potentially harmful activities before they are ready.
Alternatively, the dream could symbolize a reflection of your own inner child or immature tendencies. It may be indicating that you need to examine areas of your own life where you may be acting inappropriately or irresponsibly. This could be related to habits, actions, or decisions that are not aligned with your current stage of growth and development.
Overall, this dream suggests the need for assessment and reflection. It may be beneficial to explore the underlying emotions and circumstances surrounding your cousin's behavior in the dream, as well as analyze any relevant aspects of your own life to gain further understanding and insight.
