coma:

The movie Coma (2019), directed by Nikita Argunov, is a visually stunning Russian science fiction film that explores the concept of a shared dream-like reality. Here's a brief overview:

The story follows a young and talented architect who wakes up in a strange, surreal world after a tragic accident. This new world, called the Coma, is a fragmented, distorted version of reality, formed by the memories and dreams of people in comas. Gravity-defying landscapes, floating structures, and disjointed physics dominate this mysterious realm.

The protagonist meets a group of survivors who explain the rules of this world and the dangers posed by mysterious creatures called "Reapers." He must overcome the obstacles of the Coma and rediscover his own identity and memories in order to live. Along the way, he learns the truth about this reality, the people who are imprisoned in it, and the startling link between the real world and the Coma.

The film blends action, mystery, and philosophical questions about memory, identity, and the boundaries of human consciousness. In particular, it is commended for its creative world-building and avant-garde visual effects.
