Can a twin feel when the other dies?

Many twins share an unexplainable connection that leads some to believe they can sense when their twin is in danger or has died. This phenomenon, sometimes called twin telepathy, has fascinated people for centuries. While anecdotal accounts of twins seeming to feel their twin’s pain or distress are common, the existence of a real psychic or empathetic link remains controversial. In this article, we’ll explore what science reveals about twin bonds and whether twins can truly feel when their co-twin dies.

The Twin Connection

Twins, especially identical twins, often share an intensely close bond. This twin connection starts in the womb as twins interact and stimulate each other’s developing brains. After birth, twins are often remarkably in sync, exhibiting parallel personality traits, interests, emotions, and communication styles. Studies show that twins who are raised together seem to share an almost psychic cohesion.

Some examples of this twin connection include:

  • Finishing each other’s sentences
  • Having the same thoughts or saying the same thing at the same time
  • Feeling each other’s physical pains or emotions from a distance

Twins commonly report that they feel like they share a unique wavelength that nobody else can access. While intriguing, most scientists believe the twin bond has a biological origin, not a paranormal one.

Possible Explanations for the Twin Connection

Researchers propose several explanations for the twin connection:


Identical twins share 100% of their DNA. This genetic matching predisposes twins to very similar physical traits, personalities, interests, and mannerisms. Studies show that twins reared apart are still remarkably alike in these regards, suggesting a strong genetic component to the twin connection.

Shared Environment

Twins raised together also share nutritional, social, emotional, and other critical environmental factors that shape development. This further encourages them to behave alike and cement an intimate bond. However, this does not explain the connection seen in twins raised apart.

Mirror Neurons

These specialized brain cells activate both when performing an action and observing someone else perform that action. They allow us to “mirror” others in an almost empathetic way. Scientists theorize that twins may have more active mirror neuron systems, enhancing their abilities to intuit and mirror each other’s feelings.

Brainwave Patterns

Some studies show that the brainwave patterns of identical twins are more closely aligned than those of fraternal twins. This may enable easier communication, empathy, and mutual understanding. More research is needed to confirm if this contributes to the twin bond.

Extreme Closeness

Simply spending massive amounts of time together from birth likely forges an exceptional emotional closeness between twins. This intimacy and existing rapport could make it easier for them to predict each other’s responses, finish sentences, or share thoughts.

Can Twins Biologically Feel Each Other’s Pain?

Some twins have described feeling phantom pains or physical discomfort on the same side of their body at the same time as their co-twin. Is this true empathy or telepathy? Science suggests a biological basis for this phenomenon.

Mirror Touch Synesthesia

This condition causes someone to literally feel the physical sensations observed in others. Though rare in the general public, mirror touch synesthesia seems more common in identical twins. Researchers theorize this may stem from cross-wiring between mirror neurons and the brain’s touch perception pathways.

Shared Circulation

Identical twins sometimes share circulation in the womb, resulting in interconnected blood vessels in their brains or limbs post-birth. This unusual vascular linkage can cause both twins to experience pain when only one twin is injured. However, shared circulation is very rare.

Coincidence or Psychosomatic Response

The vast majority of twins do not have anatomical reasons for shared pain. Some researchers argue that simultaneous pain in both twins is often coincidental. Or it may be psychosomatic, with the expectation of a connection triggering physical symptoms. More rigorous research is needed on this phenomenon.

Anecdotal Accounts of Twins Sensing Death or Distress

While science has yet to confirm telepathy or extrasensory perception, many twins remain convinced they can feel when their twin needs help or has died. Some dramatic historical accounts include:

Swedish Twins

Identical twins Ingrid and Margareta Dahlén were six years old when Margareta died of an illness. At the exact moment of her death, Ingrid is said to have recognized that her twin had passed away.

Nightmares of Impending Death

Joan Woodard Cooper reported having disturbing dreams of death prior to learning her identical twin sister had been killed 3,000 miles away in a car accident.

Simultaneous Cardiac Arrests

In 2006, twin brothers aged 65 died from apparent cardiac arrest within hours of each other despite living over 300 miles apart and being unaware of the other’s illness.

Shared Grief and Funerals

Multiple bereaved twins have described feeling an inexplicable wave of grief wash over them at the moment their twin died, even before anyone informed them of the death. Some even arrange joint funerals.

However, most of these accounts are retrospective, so recall bias likely influences reports of precise timing. And without controlled scientific studies, they remain inconclusive.

Scientific Research on Twin Telepathy

A few small studies have attempted to experimentally test for physiological signs of twin telepathy with somewhat mixed results:

Heart Rate Study

A small 1977 study hooked up one twin to equipment measuring skin resistance, blood volume, heart rate, and breathing rate. Their twin was isolated in another room where researchers surprised them with noises, electrical shocks, or emotional stimuli to provoke physiological arousal. Some twins did show similar changes in heart rate at the same times, suggesting shared reactions. However, most did not.

FMRI Brain Scans

A 2015 study used fMRI imaging to examine the brain activity of 12 identical twin pairs. When one twin was shown frightening images, some of their twins showed similar activity changes in emotion processing brain regions. However, these changes were subtle and not seen consistently.

No Evidence for Heart Rate Telepathy

A more recent 2020 study measured the heart rates of 44 twin pairs during intense emotions. No evidence was found of heart rate changes in one twin correlating with the other’s emotional state.

Overall, some small studies report hints of unexplained physiological connections. But most find no concrete evidence of it. Much larger scale, rigorously controlled studies using modern neuroimaging technology are still needed.

Can Twins Sense Death Through Quantum Entanglement?

Some have speculated that twins may be able to sense each other through a psychic phenomenon called quantum entanglement. In quantum physics, subatomic particles can become inextricably linked so that actions performed on one immediately affect the other, even over great distances. Some believe the profound bond between twins may rely on a similar phenomenon.

However, most physicists reject this explanation as “quantum pseudo-science.” No compelling evidence suggests quantum effects play a significant role in biological processes, let alone explain twin bonds. Quantum entanglement also does not allow faster-than-light communication, so it could not convey an immediate awareness of death. This intriguing but unproven concept remains on the fringes of physics.

The Grief Process in Twin Loss

Regardless of psychic bonds, losing a twin is an exceptionally traumatic event. Twins often describe feeling like they’ve “lost a part of themselves.” The grief process has unique challenges:

Profound Identity Crisis

Bereaved twins struggle with losing the person who has been by their side sharing every life experience. This can trigger a devastating identity crisis.

Intense Loneliness

Twins describe acute feelings of loneliness and isolation after twin loss, missing their constant companion and confidante.


Some twins experience misplaced guilt, irrationally feeling they should have saved their co-twin or prevented the death in some way.


Depression resulting from twin loss is exceptionally severe and often resistant to treatment. Some studies show it doubles the risk of suicide. Seeking grief counseling is crucial.

Commemorating Twins Together

Having a joint funeral or memorial service allows mourning twins to honor their bond. Continuing to celebrate shared holidays or special occasions as a twin can also help the healing process.

Coping with Losing a Twin

Here are some key strategies to help twins cope with the loss of their co-twin:

Allow Yourself to Grieve Fully

The grief process cannot be rushed. Allow yourself to experience and process all the emotions as they come.

Seek Out Grief Support Groups

Connecting with other bereaved twins can provide vital empathy and support. Therapists specializing in twin loss can also help.

Focus on Your Own Life

Pursuing education, career goals, relationships, hobbies, or causes important to you gives life meaning and purpose again.

Embrace the Beautiful Memories

Cherish all the joyful memories you shared instead of regret over the loss. Your twin lives on in your heart.

Take Care of Yourself

Make self-care a priority through healthy eating, rest, exercise, and social connection. Give yourself permission to heal.


The idea that twins share an unbreakable empathetic connection or can psychically sense each other’s distress continues to captivate the public imagination. However, scientific evidence for twin telepathy remains slim to non-existent. Most researchers argue that twins’ uncanny bonds rely not on the paranormal but on far more natural biological factors.

While we cannot definitively rule out that some twins do experience unexplained links, the majority likely do not. Yet the profound intimacy and reliance on each other most twins share from birth undoubtedly leaves an indelible imprint. Losing one’s twin severs a lifelong attachment vital to one’s identity. The excruciating grief that follows, while difficult to bear, often affirms just how precious that relationship was.
