“Khawab Mein Gadhy Ka Dhoodh Peena” means you will be affected if you drink milk from a mare or a donkey. There is no good tabeer in this khwab. The dreamer should be careful about his health and he shouldn't neglect it if he is doing so. Indeed, health is one of the greatest blessings of Allah Almighty.
اگر کوئی خواب میں دیکھے کہ گدھی کا دودھ پیتا ہے تو دلیل ہے کہ بیمارہوگا اور پھر شفاء پائے گا۔
The dreams are the indicators of affecting the health of the person. According to this dream when someone sees himself or herself drinking the milk of a donkey, it means that he is going to suffer from a severe disease. However, some interpreters have given it a reflection of getting healthier.
