**Yes, it's real.** The **"Russian Doll"** is a real Russian nesting doll (also called a Matryoshka doll), and the concept of **"Russian Doll"** as a psychological horror story has been done many times. The original idea comes from the short story "Don't Go There" by **Jason Pargin**, published in 2010. It's about a guy who gets trapped inside one of these dolls, reliving his traumatic childhood over and over. The story was later adapted into a popular **Netflix series** called "Russian Doll," which premiered in 2019. The show follows the character Nadia Vulvokov (played by **Natasha Lyonne**) as she navigates her own dark past while trapped inside one of these dolls. It explores themes of trauma, addiction, and self-discovery through a surreal and often disturbing metaphor. There have been several other short stories and anthologies that use the "Russian Doll" concept — often with similar ideas of psychological horror and character introspection. So yes, it's not just some random idea; there's actual existing work based on this concept.
