To dream that you are swelling up symbolizes a growing problem or issue. You need to address the situation before it gets out of hand. Consider the object or body part that is swollen for additional significance. Alternatively, the dream may be a pun on something that is going "swell". Or it may be a metaphor of your over-inflated ego.

To dream that you see yourself swollen, denotes that you will amass fortune, but your egotism will interfere with your enjoyment. To see others swollen, foretells that advancement will meet with envious obstructions.
