Have you ever felt that the world around you is unreal, a toy, and that you had a total disconnect with yourself?.. Depersonalization and derealization - almost every person has experienced these conditions in their life when they find themselves in a stressful situation. However, there are people among us for whom these sensations are permanent, who for a long time or always remain in their own world, woven from alienation and detachment from reality and from themselves. This book contains stories of just such heroes. How does it feel for them or for us? How to help and how not to harm? From the horse's mouth: welcome to the deep waters - and put on your submersible... We begin the dive.
