The Selling of a Disliked Item
Scholars have said that if one sees themselves selling a disliked item, there is no good in it. However, if they buy a beloved item, that action may indicate salvation from what they fear, whereas buying a disliked item may signify an error that brings sorrow and grief to the dreamer.
