Fermentation in a dream signifies that your body’s gastric juices are out of balance. You may be feeling bloated or gassy, or experiencing indigestion from overeating.
You may have ingested something that did not agree with you and are now experiencing some of the illness’ symptoms.
Fermentation in a dream can represent the process of fermentation itself. You may be visualizing wine, beer, or bread dough rising and expanding as it ferments. This suggests that an idea has been evolving in your mind and is getting ready to burst into life.
An example of fermentation in a dream could be someone who is experiencing change or growth and wants to stand out from the rest of the crowd. It could also be someone who is going through an experimental phase in life and is not sure how it will turn out.
