Dissociative Identity Disorder: what is life like for people with multiple personalities?

Introduced to many on social media via influencers such as @we.are.olympe, or in a fictionalized form in the movie Split (2016), Dissociative Identity Disorder (DID) can be both fascinating and frightening. But for those who live with several “alters” in one body, it is mainly a psychic protection mechanism that follows extreme traumas such as repeated sexual violence during childhood. Classified by the WHO, it affects nearly 1% of the population to varying degrees. However, even within the scientific community, DID is still not widely recognized.
