Neuroscientists and psychologists are exploring the field of dream engineering, using sensory stimulation to influence the content of people's dreams. By manipulating sounds, smells, touch, and movements, researchers have achieved benefits such as improving sleep quality, mood, learning, and creativity. Dream-induction devices are being developed for home use, but concerns about potential misuse and ethical implications have been raised. While the potential for dream engineering is exciting, caution is urged to ensure the protection of sleep and prevent unwanted manipulation. [Extracted from the article]
