Cooking meat in a dream

I did isthikhara for my marriage. I saw in a dream that I was opening a shopping beg and taking out leg piece of mutton. I was happy to see that clean and ready to cook mutton, I realized that someone was cooking by my side and putting meat in cooking pot. I thought I should start cooking too. I was thinking should I remove that white piece of fat from it or not. But then I decided to cook the leg piece as a whole with that white fat on it. The cooking pot was small but I managed to put the leg piece in it and I thought it would take few hours to cooked completely. I was feeling happy that I can eat that after few hours. Could you please tell me that is it a positive dream or negative? Should I go for that proposal or not?
