Drowsiness in a dream means that you are finally going to fix your mild-insomnia problems. But , this is not the main reason why you are dreaming that you are sleeping.
This dream also means that you are finally going to pay attention to minor things that you have been missing out on lately. You are going to wake up and start paying attention to everything that you have missed, and you are going to feel good about it.
You will become aware of opportunities that you weren’t aware of before as well, and those opportunities will bring many benefits for a while.
