Trade
To dream of making a trade represents the exchange of ideas. Alternatively, a trade may reflect a compromise or changing of choices.
Negatively, trading in a dream may be a sign that you are consciously wasting your time exploring ideas or possibilities that you have no interest in. Compromising too much or not sticking to what you really want in a situation.
Example: A man dreamed of sitting in a living room and trading wives with another man. In waking life he was exchanging spiritual ideas with another person. Both were recommending books to each other with ideas the other had heard before.
