Seeing, hearing, or sensing someone who has died is most commonly called a grief hallucination, or more formally, a post-bereavement hallucinatory experience (PBHE). If this has happened to you, you’re far from alone: a meta-analysis of research on the topic estimates that more than 56% of bereaved people experience some form of hallucination involving a deceased loved one. These experiences occur in people with no history of mental illness and are widely considered a normal part of grief rather than a sign of something wrong.
The Clinical Names for This Experience
Researchers and clinicians use several overlapping terms. “Post-bereavement hallucinatory experience” is the broadest clinical label, covering any sensory experience of someone who has died. You’ll also see it called a “grief hallucination,” a “hallucination of widowhood” (an older term from early studies of widows and widowers), or simply a “bereavement hallucination.” The American Psychiatric Association recognizes hallucinations of the deceased’s presence, such as seeing them sitting in a favorite chair, as a feature associated with grief.
Another commonly used term is “sense of presence,” which describes the strong feeling that the deceased person is nearby even when you don’t literally see or hear them. Some people use the word “visitation,” particularly in spiritual or religious contexts, to describe the same phenomenon without the clinical framing.
How Common It Really Is
The numbers are striking. A systematic review and meta-analysis pooling data across multiple studies found that an estimated 56.6% of bereaved people experience at least one bereavement hallucination. When broken down by specific senses, prevalence ranged from about 7% to nearly 40% depending on the type of experience. That means more than half of people who lose someone close will, at some point, sense that person’s presence in a way that feels vivid and real.
Many people never mention these experiences to anyone, often because they worry it sounds strange or because they fear being told something is wrong with them. The research suggests the opposite: these experiences are so common that not having them may be the less typical response to significant loss.
What These Experiences Feel Like
Bereavement hallucinations aren’t limited to seeing a person. They span every sense. Some people hear the deceased person’s voice calling their name or speaking a familiar phrase. Others catch a whiff of their perfume, cologne, or the smell of their cooking. Some feel a physical sensation like a hand on the shoulder or the weight of someone sitting on the edge of the bed. And many people experience the general sense of presence, a powerful, unmistakable feeling that the person is in the room, without any specific sensory detail attached to it.
Visual experiences tend to be the type people find most startling. You might briefly see the person standing in a doorway, sitting in their usual spot, or walking ahead of you on the street. These moments are typically fleeting, lasting seconds, and the person usually recognizes almost immediately that the vision isn’t real. That awareness is one of the key differences between a grief hallucination and a hallucination associated with a psychiatric condition.
Why the Brain Does This
Your brain is constantly making predictions about the world based on patterns it has learned. When you’ve shared years of daily life with someone, your brain builds deep, automatic expectations: that voice in the kitchen, that shape in the hallway, that scent on a pillow. After a death, those neural patterns don’t vanish overnight. The brain keeps generating predictions based on thousands of past experiences, and sometimes those predictions briefly override what your senses are actually receiving.
Research into the neuroscience of hallucinations more broadly has found that they involve the brain’s lower-level sensory processing regions holding onto information longer than usual. In other words, the parts of the brain responsible for basic perception, things like recognizing shapes, sounds, and textures, become slightly overactive or slow to update. In grief, this likely means the brain keeps “filling in” sensory details of the missing person because the pattern of their presence was so deeply encoded.
Grief Hallucinations vs. Prolonged Grief Disorder
On their own, bereavement hallucinations are not a disorder. They don’t require treatment, and most people find them comforting or at least neutral. However, they can sometimes occur alongside a condition called prolonged grief disorder, which the American Psychiatric Association added to its diagnostic manual in 2022.
Prolonged grief disorder involves intense longing for the deceased, difficulty believing the death actually happened, emotional numbness, feeling that life is meaningless without the person, and a disrupted sense of identity, as though part of yourself has died too. These symptoms persist at a level that significantly interferes with daily functioning well beyond what would be expected given the person’s cultural context. The hallucinations themselves aren’t what define the disorder. It’s the broader pattern of being unable to reintegrate into life that distinguishes prolonged grief from the painful but typical process of mourning.
How Different Cultures Interpret It
Whether you call it a hallucination, a visitation, or a sign depends heavily on your cultural and spiritual background. In many traditions, sensing the dead is not only normal but expected and welcomed. Some cultures view the deceased as continuing to exist in a meaningful way, with about 55% of people in one cross-cultural study describing death as a form of continuity rather than an ending. Parents often refer to a deceased child as an “angel.” In Portuguese-speaking cultures, the concept of “saudade” captures the deep, bittersweet longing for someone who will never return, a word with no direct translation in other languages.
These cultural lenses matter because they shape whether the experience feels frightening or meaningful to the person having it. Someone who believes their loved one visited them from an afterlife may draw comfort from the experience in a way that someone with no such framework might not. Neither interpretation is more correct. What the research consistently shows is that the underlying experience, sensing someone who has died, crosses every cultural boundary.
When These Experiences Are Distressing
Most people who experience grief hallucinations find them either comforting or emotionally neutral. But for some, they can be upsetting, especially if the hallucinations are frequent, if the death was sudden or traumatic, or if the person feels isolated in their grief. The distress usually isn’t about the hallucination itself but about what it stirs up: the fresh reminder of the loss, the confusion about what’s happening, or the fear of being judged for talking about it.
If these experiences are causing you significant anxiety or if they’re accompanied by the broader symptoms of prolonged grief, such as feeling unable to function, emotional numbness lasting many months, or a persistent sense that your life no longer has meaning, grief-focused therapy can help. Approaches designed specifically for complicated grief work on helping you process the loss while rebuilding a sense of purpose and connection. The goal is never to “stop” the hallucinations but to address the pain surrounding them.
For the majority of bereaved people, though, knowing that this experience has a name, that it’s remarkably common, and that it reflects how deeply your brain encoded another person’s presence is often the most useful thing to learn.
