To dream of having B.O.
(body odor) suggests you are experiencing some overwhelming anxiety, stress, fear, or nervousness in your life.
The dream may be a reminder that in order to achieve your goals, you will have to put in a lot of effort and struggle. This dream is also common when the dreamer is sick, especially with a cold or the flu.
If somebody else has B.O. in your dream, you might have hand to stand up for yourself recently in an uncomfortable situation. Or, a certain unpleasant memory is trying to come to the forefront.
