Should I pursue photography or stay in engineering?

I have done engineering but could not get a job. My hobby is photography and I have applied for photography course in a university and I did istikharah for it. I asked whether I should go for photography or not because if I go for photography course it will be difficult to return back to engineering. In my dreams I saw 2-3 children asking me what I am holding in my hand, and when I saw my hand, I was holding a camera with me. Suddenly then I was at another place, I as wearing white kurta pajama and all people around me were wearing white dress probably white kurta pajama. But I did not remember whether I was attending a marriage or funeral ceremony. Please interpret my dream.
