The text means people can become stuck and unable to move forward or progress in their lives. In this case it is due to past traumas, but that's not always the reason for the stagnancy. Here are a couple of other examples using "slump" in the same way: 1. He really hates his job but he doesn't quit. He would rather stay stuck in a slump than change his work situation. 2. The soldier is suffering from severe depression and the slump she's in makes it difficult to live her life and get to know others.

A "Slump" is like a Shortcoming, a phase of low energy, a hardship. Example: The football team recently overcame a slump given that they had trained very hard for weeks. In African American Vernacular English, we also use this word as slang to refer to someone's state of appearance or energy level. Example: Homie has been looking slump lately

"I believe that sometimes we come into a slump in our lives where we get so caught up in past trauma that it can take over our present." "Slump" here means a period where your progress slows down. It can be mild or severe. It need not be serious.
