Scientists are exploring “dream engineering,” a technique that implants cues during sleep to guide people toward experiencing specific content in their dreams. Research indicates this technology could not only enhance learning abilities and creativity but also alleviate trauma and anxiety.
American author Will Dowd, who lost his reading ability due to a degenerative disease, used “dream incubation” technology to play poetry recordings while falling asleep. This successfully made his dreams vivid and creative, even becoming material for his new book. The Dormio device, developed by a research team from MIT and Harvard, monitors physiological signals before sleep and plays voice prompts. Over 70% of participants reported dreaming about specific content. Researchers believe this technology could be used in the future to help patients with PTSD, generalized anxiety, and depression.
Existing cases also demonstrate dreams’ potential for psychological healing. After breast cancer surgery, California resident Mare Lucas ended years of nightmares and improved her emotional well-being through positive dreams induced during anesthesia. Researchers hope to establish “dream clinics” to assist those needing psychological support.
However, dream engineering also raises ethical concerns. In 2021, the American beer brand Coors launched a dream incubation advertisement, attempting to implant its brand image into consumers’ dreams, which drew criticism from multiple scientists for violating personal privacy.
Commentary:
While dream incubation technology can provide pre-sleep prompts to boost creativity, enhance memory, and even show promise in post-traumatic psychological healing, sleep remains the ultimate psychological sanctuary—a crucial time for individuals to restore mind and body and maintain psychological autonomy. Manipulating dreams for commercial purposes risks violating personal privacy and undermining sleep’s intrinsic value. With technology still immature, it may also trigger adverse psychological effects like intensified nightmares or emotional turmoil. Establishing stringent ethical guidelines and usage boundaries is therefore imperative. Only under proper regulation can dream engineering evolve into a significant technological innovation while delivering effective psychological support to those in need.
