Throughout human history, the concept of “dream sharing” has captivated our imagination. From the multi-person dream scenarios in the movie Inception to real-world scientific attempts to establish communication during sleep, dream-sharing technology is moving from science fiction to reality. Dream sharing refers to the use of advanced technological methods to allow multiple individuals to perceive, communicate, and even participate in each other’s dreams. In 2024, remarkable breakthroughs have been made in this field: researchers have utilized brain-computer interface (BCI) technology, virtual reality (VR), and augmented reality (AR) to enable inter-personal communication during sleep and the recording and reconstruction of dream content. These advances not only reveal new possibilities for connecting the human brain with the digital world but also raise psychological considerations, such as how dream sharing influences perception and mental health, particularly for low-vision users. This article explores the latest developments in dream-sharing technology from both a technological and psychological perspective and examines its potential impact on low-vision users.
Advances in Dream Sharing Technology
Communication in Dreams via Brain-Computer Interface (BCI)
In September 2024, the Silicon Valley startup REMspace achieved a historic breakthrough: the first-ever successful communication between two individuals in a dream. Researchers monitored participants’ brain waves and physiological signals during sleep to detect when they entered a lucid dreaming state. When the first participant entered REM sleep, the system transmitted a randomly generated dream word, “Remmyo,” via an earbud. The participant then repeated the word in the dream, and facial electromyography sensors captured their speech, sending it to a central server (HK01.COM). A few minutes later, the second participant, also in REM sleep, received this word through their own earbud. Upon awakening, both confirmed that they had successfully “spoken” in a dream. This milestone in inter-dream communication is expected to open doors to applications in mental health treatment, skill training, and immersive entertainment (CN.DATACONOMY.COM).
Recording and Reconstructing Dream Content
Another major advancement in 2024 was the improvement of dream-recording technology. A team from Kyoto, Japan, developed a system capable of interpreting and reconstructing dream imagery using functional magnetic resonance imaging (fMRI) and artificial intelligence (INDIATODAY.IN). The system analyzed sleeping participants’ brain activity and matched neural signals with an image database. Experiments showed that this method could predict dream content with about 60% accuracy, with over 70% accuracy for specific objects (INDIATODAY.IN). Although the clarity and precision of dream reconstruction still require refinement, this “dream recording device” marks a step toward translating dreams into visible representations, potentially benefiting neuroscience and psychological research.
Virtual/Augmented Reality and Dream Interaction
Beyond recording and communication, researchers are also investigating the integration of dreams with reality. In March 2024, a REMspace experiment demonstrated that a lucid dreamer could control real-world smart home devices while dreaming (SLEEPREVIEWMAG.COM). The participant, wearing a brain-monitoring device, issued mental commands in their dream, successfully turning on lights, boiling water, and playing the radio through a smart speaker (SLEEPREVIEWMAG.COM). Other studies revealed that dreamers could manipulate virtual objects, such as steering virtual cars and controlling video game characters, suggesting that the boundary between dreams and reality is becoming increasingly blurred (CN.DATACONOMY.COM). Additionally, the concept of “dream weaving” was introduced, proposing that synchronized brainwave devices could enable multiple individuals to enter a shared dream environment (ENTECHONLINE.COM). This innovation could have applications in entertainment, social interaction, and education, allowing users to collaborate in a dream setting.
Dream Sharing and the Low-Vision Experience
For low-vision or blind individuals, dreams hold unique significance. Many congenitally blind individuals construct dreamscapes using auditory, tactile, and olfactory cues rather than visual imagery (HKSB.ORG.HK). In contrast, people who lost their vision later in life often continue to “see” in their dreams, as their visual memory persists. One low-vision individual shared: “I dreamed of my past job as a salesperson and could clearly see my customers’ faces” (HKSB.ORG.HK). Surprisingly, some congenitally blind people report “seeing” objects in their dreams, suggesting the brain’s capacity to generate visual-like experiences.
Dream-sharing technology holds particular promise for low-vision users. If dreams can be recorded and reconstructed, visually impaired individuals might “see” their own dreams through tactile images or audio descriptions. Alternatively, BCI implants could transmit dream-based visual signals to the brain’s visual cortex, potentially offering an experience of sight similar to developments in BCI-assisted vision restoration (YOUTUBE.COM). Furthermore, shared dreams could allow low-vision individuals to participate in dream experiences created by sighted individuals, fostering inclusivity and emotional connection.
Psychological Perspectives: The Impact of Dream Sharing on Mental Health
Dreams have long been associated with emotions and cognition. Psychological research suggests that discussing and sharing dreams enhances empathy and social bonding (NEUROSCIENCENEWS.COM). Swansea University researcher Mark Blagrove found that narrating and analyzing dreams with others strengthens interpersonal relationships (NEUROSCIENCENEWS.COM). For low-vision individuals, dream sharing can serve as a platform for expressing their unique sensory perceptions and fostering a sense of social inclusion.
Dream-sharing technology may also have therapeutic applications. Lucid dreaming therapy is already used to treat post-traumatic stress disorder (PTSD) by enabling patients to alter nightmares (HEALTHLINE.COM). With dream-sharing tools, therapists could potentially enter patients’ dreams to provide guidance or help them face fears in a controlled dream environment. This method could assist individuals with disabilities in overcoming psychological challenges by reinforcing positive dream experiences that translate into real-life confidence.
However, ethical concerns must be addressed. Dreams often contain deeply personal thoughts and fears, and sharing them raises privacy issues (ENTECHONLINE.COM). Additionally, overreliance on dream-sharing experiences may blur the distinction between dreams and reality, potentially leading to escapism. Psychological support should accompany dream-sharing technologies to ensure their responsible and beneficial use.
Conclusion: Looking Ahead with a Critical Eye
The advancements in dream-sharing technology in 2024 mark a turning point from science fiction to practical applications. From REMspace’s inter-dream communication breakthrough to Japan’s dream reconstruction technology and the integration of VR and BCI, these innovations hold immense promise—especially for low-vision users. Dream-sharing could bridge the sensory gap, offering unprecedented access to visual experiences. However, scientific rigor remains crucial; many findings require further validation, and ethical guidelines must be established to protect user privacy and mental well-being. As technology progresses, dream-sharing may revolutionize communication, therapy, and social interaction, providing new hope for low-vision individuals by granting them a more inclusive, immersive sensory experience.
