👉 In psychology, a possessionist is someone who has a strong attachment to their possessions and often feels possessive of them. They may be overly concerned with maintaining their possessions and may view losing or damaging them as a negative consequence. Possessing something can also be seen as an act of dominance or control over others. This concept is often associated with the idea of having a "power" over someone else, especially in relationships where they are considered to have control over the other person's actions.
