Dreams are a natural part of human experience that usually occur during sleep when the brain is at rest. But what happens when the brain is in a state of severe impairment, such as in a coma? A coma is a state in which a person remains unconscious for a long time, usually due to a serious injury or illness. In this state, brain activity is reduced, but can a person still dream?
Understanding the reality of dreaming in a coma is important because it can help illuminate the deeper mechanisms of brain function and consciousness. In 2025, recent advances in neuroscience and neurotechnology are helping to understand the relationship between brain function and dreams in a coma state. These discoveries will not only improve medical treatments but also help in understanding the human mind.
The past decade has seen significant progress in understanding brain function in coma. Technologies such as functional magnetic resonance imaging (fMRI) and electroencephalography (EEG) have helped to examine what brain activity is happening when patients are unconscious. With these technologies, researchers can now see which brain regions remain active even in coma—raising philosophical questions similar to those explored in The Ending of The Giver, where the line between consciousness and unconscious experience becomes deeply symbolic.
Recent research has shown that the thalamus, which controls sensory information, is more active in some coma patients, indicating that the brain is processing sensory information to some extent. However, the question remains whether this activity translates into dreams.
Artificial intelligence (AI) has revolutionized neuroscience. AI algorithms are being used to analyze EEG and fMRI data to determine which brain activities may indicate dreaming or waking up. AI has made it possible to analyze large amounts of data, which has reduced the number of errors in research results.
Additionally, AI is being used to predict the recovery of coma patients. AI analyzes brain scans and patient data to help predict how likely a patient is to regain consciousness.
fMRI is a key technology used to examine brain activity during a coma. This technology measures changes in blood flow to show which parts of the brain are more active. By analyzing this data, researchers try to determine whether these activities are related to dreaming.
The EEG records the electrical activity of the brain and is commonly used to monitor coma patients. It analyzes brain waves to determine the patient’s level of consciousness. Researchers use EEG to see if a coma patient is experiencing REM sleep, which occurs during dreaming.
AI systems are being used to analyze the brain activity of coma patients. These systems interpret EEG and fMRI data to detect brain patterns that may suggest dreaming. Interestingly, some researchers compare this complex brain analysis to how veterinarians might study symptoms in unusual cases, such as a dog with worms’ poop, where hidden signs must be decoded carefully. In both cases, AI helps uncover invisible clues—whether in a pet’s digestive health or the unconscious mind of a patient—to better understand what might be happening beneath the surface.
Using advanced neuroimaging technologies such as fMRI and EEG, doctors can see what the brain activity of a coma patient is like, and whether they are experiencing any kind of dreaming or consciousness.
AI is being used to diagnose patients with mental illnesses such as epilepsy. AI is also being used to see if coma patients are experiencing any kind of dreaming.
BCI technologies are providing communication methods for patients with brain injuries or comas. Although they are not directly related to dreaming, these technologies help in analyzing brain activity.
AI is being used to predict the recovery of coma patients by analyzing their brain data. This is used to assess whether the patient can regain consciousness or not.
Better understanding of consciousness: Neuroimaging and AI technologies have made significant advances in understanding brain function, allowing us to better understand dreams in comas.
Improvement in patient care: These technologies allow doctors to monitor a patient’s brain activity in real time, which improves their treatment decisions.
Possibilities for new treatments: As AI and neuroimaging technologies improve, new treatments such as brain stimulation therapies may be introduced for coma patients.
Ethical issues: The use of AI may raise issues regarding the security and privacy of patient personal data.
Limitations of current technology: Although neurotechnology is advancing, we have not yet been able to prove whether coma patients are dreaming or not. Reports from Global News 9 have highlighted how even the most sophisticated brain-scanning tools still fall short of fully unlocking the mystery of consciousness in coma states.
High costs: Advanced technologies such as fMRI and AI analyses are expensive, which can limit their accessibility.
Do coma patients dream?
Some studies have suggested that coma patients may have dream-like experiences, but this has not yet been proven.
How do coma patients’ brains work?
fMRI and EEG technologies help analyze brain activity to see where the brain is active during a coma.
How does artificial intelligence help diagnose coma patients?
AI analyzes brain activity to predict whether a coma patient will regain consciousness.
Can coma patients hear or feel anything?
Sometimes coma patients may have some sensory awareness, but this condition may vary from patient to patient.
How is coma patients predicted?
AI and neuroimaging technologies predict the likelihood of a patient regaining consciousness by analyzing brain activity.
The question of dreaming in coma is still a mystery, but recent advances in neuroscience and neurotechnology are helping to better understand it. As AI and neuroimaging technologies continue to improve, we will be able to get a more accurate answer to this question. In the future, these technologies will not only improve the care of coma patients, but also could revolutionize the treatment of brain injuries and diseases of consciousness.
