In order to get out of the daily routine, people often have dreams where they are doing something different. In this case, the dreamer ate a lot of donuts. This can be interpreted as a person indulging themselves in things that are not good for them.
The idea behind this interpretation is that if you eat donuts in your dreams, then you might be trying to escape from something hard or trying to reward yourself for something hard you’ve done.
Donuts represent comfort and happiness in our lives but if we eat too many donuts, we will gain weight and our health will suffer. Eating donuts in dreams can also mean that something is being denied to us or we are escaping from hardship by indulging in something sweet.
