"inception" as depicted in the 2010 science fiction film of the same name does not exist in reality. In the movie, "inception" refers to the concept of planting an idea into someone's mind while they are in a dream state.
While dreams and the study of consciousness remain fascinating topics for researchers, we have not yet achieved the level of dream manipulation portrayed in the film. The science behind dreams, sleep, and consciousness is still a subject of ongoing research, and our understanding of these phenomena continues to evolve.
It's important to remember that movies often explore fictional and speculative ideas that go beyond current scientific capabilities, and "Inception" is no exception. While there have been advances in neuroscience and the study of dreams, the ability to consciously control or manipulate someone's dreams to the extent shown in the movie remains a work of fiction.
