For dissociative systems, boundaries can be more complicated. Some system members may be unaware of internal boundaries and therefore unintentionally ignore them. System members may also differ in what they believe are reasonable or necessary boundaries.
A trauma history can impact boundaries as well. Many people with complex trauma in childhood were never shown healthy boundaries or allowed to have any. Some parts may remember that they were punished for trying to have boundaries as a child and are understandably leery of having any now. Other parts may have learned that people-pleasing was a way to stay safer, and those same impulses can override intended boundaries in adulthood.
This page is part of the How Do Boundaries Function in Dissociative Identity Disorder section of the CommuniDID site, which explains why limits may feel unsafe, how parts react differently to boundaries, and how boundary-setting supports stability and identity.
