Many people wonder what happens after death. Near-death experiences (NDEs) often offer a glimpse of something extraordinary that clearly falls outside the everyday.
These are moments when someone — sometimes after cardiac arrest or another medical emergency — has an experience that feels as though it takes place in another reality. Even without clinical death, such an experience can occur, depending on how you define the concept.
Research shows that merely thinking about death can have a noticeable effect on our behavior. In some studies, for example, it was found that when people were reminded of their mortality, they initially withdrew somewhat or identified more strongly with their own group.
But those who reflect on death more frequently and consciously show more pro-social behavior and feel more connected to others. The awareness of finitude can make life richer, a principle known in philosophical traditions as memento mori.
For many people, an NDE profoundly changes their view of life. The experience sometimes resembles waking from a dream, but with memories that feel lasting and vivid.
According to some thinkers, including Bernardo Kastrup, such an experience can show that death is not an absolute ending, but rather the end of a certain form of separation from the whole of which we are part.

What Are Near-Death Experiences (NDEs)?
Near-death experiences (NDEs) typically occur when someone is physically in mortal danger, such as during cardiac arrest. Yet there are also cases where no clinical death takes place, but the experience is substantively the same. People often describe it as if they temporarily find themselves in another reality: an atmosphere of light, peace, or deep connection that sharply differs from everyday consciousness.
Bernardo Kastrup’s Perspective
According to philosopher Bernardo Kastrup, death is the end of a process he calls dissociation: the phenomenon in which a part of consciousness experiences itself as a separate ‘self,’ isolated from the whole.
After death, that separation disappears, but memories of life remain as a coherent network of experiences, a so-called life complex. He compares this to waking from a dream: the ‘dream character’ ceases to exist, but the memory of the dream — and the feelings associated with it — remains intact.
In the view of analytic idealism, reality is essentially mental in nature. The physical world is then a manifestation of consciousness, not an independent material entity. The disappearance of the illusion of separation can thereby shift your entire perspective on life and death.
What Happens After Death?
When dissociation dissolves, according to this approach, you experience anew the full context of which you were always part. The perspective of the ‘self’ from your life remains present as memory, but the realization that it was only a temporary role becomes clear. This forms the life complex: a web of personal memories and associated feelings that persists outside time and space.
Research suggests that memories have no physical storage location in the brain; rather, the brain functions as a gateway to this information. Therefore, according to Kastrup, there is no reason to assume they disappear upon physical death.
The Concept of Dissociation
Dissociation creates during life a clear boundary between personal consciousness and the so-called mind at large — the larger whole of consciousness. At death, that boundary dissolves. What remains is a fully integrated consciousness, but with the preservation of the perspective from which life was experienced.
Many people with an NDE describe experiencing a ‘body of light’ in this state. Within the hierarchy of dissociation, this can be seen as a symbolic representation: consciousness seeks a recognizable form to represent itself, even when there is no physical manifestation.

Near-Death Experiences (NDEs) and Brain Activity
In the final moments of the dying process, a sudden increase in brain activity has been measured in some people, particularly in the gamma wave range. These waves are associated in neuroscience with consciousness, memory, and heightened perception.
Research — both in humans and animals — shows that this surge can occur while the person already appears clinically dead. The phenomenon shows superficial similarities to psychedelic experiences, though here it involves a brief intensification of brain activity, whereas psychedelics often come with a decrease.
Bernardo Kastrup sees this peak as possibly related to the dissolution of dissociation: a moment when the full reality of consciousness breaks through and is experienced intensely.
He refers to Steve Jobs’ final, repeatedly spoken “oh wow” as an example of a possible first reaction to that regained perspective. It may be a physical manifestation of an inner transition, but according to him, it does not explain the entire phenomenon of NDEs.
Implications for Organ Donation
In organ donation, organs are removed from a body that is often still in the early stages of the dying process. Within the framework of analytic idealism, organs are seen as the external manifestation of mental processes.
These processes are largely autonomous during life and not intertwined with the personal ‘self,’ so you don’t identify with them either. Therefore, according to Kastrup, there is no reason to think that donating organs ‘anchors’ you to physical existence after death.
Kastrup considers it plausible that organs, as carriers of autonomous mental processes, can subtly influence the consciousness of the recipient. This could broaden their sense of identity by allowing them to experience aspects that lay outside their original self-image.
Dying as a Gradual Process
Both in medical observations and in personal experiences, death rarely proves to be a sudden event; it is often a process that unfolds over hours or even days. The body may still show signs of life — such as breathing or heartbeat — while consciousness may have already shifted to another state.
Kastrup compares it to a footprint in wet sand: when the force that made the imprint disappears, the trace remains visible for a while, until it gradually fades. Metabolism decreases, organs stop in phases, but the whole does not extinguish all at once.
Symbolism in Near-Death Experiences (NDEs)
Many people describe during an NDE that they experience a body of light, or that they meet loved ones or deceased relatives. Within analytic idealism, this can be seen as symbolic communication of consciousness with itself.
Just as in dreams, the mind chooses recognizable images to represent a deeper reality. A body of light then functions as a ‘residual form’ of one’s own identity, without any physical presence.
The Role of Memories After Death
According to Kastrup, there is no evidence that memories are physically stored in the brain. The brain functions rather as a gateway to this information. When the dissociation of life disappears, a web of experiences and feelings remains: the life complex.
Just as a powerful dream can stay with you, complete with feelings and associations, a life can persist as a complex — outside time and space, and without the core of those experiences being lost.
Possible Psychological Effects of Organ Donation
Within the framework of analytic idealism, this would be explicable: organs are manifestations of mental processes that work autonomously during life. When placed in another body, this can lead to new, unexpected connections in the recipient’s experience.
Conclusion
Scientific research confirms that death is not a sudden ‘on/off’ event, but a gradual process. Near-death experiences (NDEs) show that the end of dissociation does not mean the loss of what is essential.
Personal agency may disappear, but the network of memories and experiences — the life complex — persists. For those willing to consciously reflect on death, that realization can actually stimulate a richer and more connected life.

Frequently Asked Questions
What is an NDE?
A near-death experience (NDE) is an intense state of consciousness that occurs when someone is close to death, for example during cardiac arrest. People often describe feelings of peace, seeing light, or experiencing themselves outside their body.
Are all NDEs the same?
While core experiences often overlap — such as a sense of leaving the body or encounters with deceased loved ones — details vary depending on cultural background, personal beliefs, and context.
How does analytic idealism explain NDEs?
According to analytic idealism, NDEs are moments when the normal ‘separation’ between personal consciousness and the larger whole temporarily disappears. The physical world is viewed in this philosophy as a manifestation of consciousness, making such experiences consistent with a non-material interpretation of reality.
Is increased brain activity during dying the cause of an NDE?
During dying processes, a peak in gamma waves has sometimes been measured, associated with consciousness and memory. This may be a physical reflection of the transition, but it does not explain all aspects of NDEs. Many researchers believe more is at play than brain activity alone.
Can donor organs transfer memories or personality?
Some recipients report subtle changes after transplantation. Within analytic idealism, this is seen as a possible influence of autonomous mental processes that come with the organ. This effect is rare and usually experienced positively.
