Parapsychology is a field of research that studies a number of ostensible paranormal phenomena, including telepathy, precognition, clairvoyance, psychokinesis, near-death experiences, reincarnation, and apparitional experiences.

An epiphany is an experience of a sudden and striking realization. Generally the term is used to describe a scientific breakthrough or a religious or philosophical discovery, but it can apply in any situation in which an enlightening realization allows a problem or situation to be understood from a new and deeper perspective. Epiphanies are studied by psychologists and other scholars, particularly those attempting to study the process of innovation.

The psychology of self is the study of either the cognitive, conative or affective representation of one's identity, or the subject of experience. The earliest form of the Self in modern psychology saw the emergence of two elements, I and me, with I referring to the Self as the subjective knower and me referring to the Self as a subject that is known.

Near-death studies is a field of psychology and psychiatry that studies the physiology, phenomenology and after-effects of the near-death experience (NDE). The field was originally associated with a distinct group of North American researchers that followed up on the initial work of Raymond Moody, and who later established the International Association for Near-Death Studies (IANDS) and the Journal of Near-Death Studies. Since then the field has expanded, and now includes contributions from a wide range of researchers and commentators worldwide. Research on near-death experiences is mainly limited to the disciplines of medicine, psychology and psychiatry.

A flashback, or involuntary recurrent memory, is a psychological phenomenon in which an individual has a sudden, usually powerful, re-experiencing of a past experience or elements of a past experience. These experiences can be frightful, happy, sad, exciting, or any number of other emotions. The term is used particularly when the memory is recalled involuntarily, especially when it is so intense that the person "relives" the experience, and is unable to fully recognize it as memory of a past experience and not something that is happening in "real time".

The International Association for Near-Death Studies (IANDS) is a nonprofit organization based in Durham, North Carolina in the United States, associated with near-death studies. The Association was founded in the US in 1981, in order to study and provide information on the phenomena of the near death experience (NDE). Today it has grown into an international organization, which includes a network of more than 50 local interest groups, and approximately 1,200 members worldwide. Local chapters, and support groups, are established in major U.S cities. IANDS also supports and assists near-death experiencers (NDErs) and people close to them. In one of its publications the organization has formulated its vision as one of building "global understanding of near-death and near-death-like experiences through research, education, and support".

Hyperthymesia, also known as hyperthymestic syndrome or highly superior autobiographical memory (HSAM), is a condition that leads people to be able to remember an abnormally large number of their life experiences in vivid detail. It is extraordinarily rare, with fewer than 100 people in the world having been diagnosed with the condition as of 2021. A person who has hyperthymesia is called a hyperthymesiac.

Pre-lucid dreaming is the beginning stages of inducing the lucid dreaming process. At this stage, the dreamer considers the question: "Am I asleep and dreaming?" The dreamer may or may not come to the correct conclusion. Such experiences are liable to occur to people who are deliberately cultivating lucid dreams, but may also occur spontaneously to those with no prior intention to achieve lucidity in dreams.

Pam Reynolds Lowery, from Atlanta, Georgia, was an American singer-songwriter. In 1991, at the age of 35, she stated that she had a near-death experience (NDE) during a brain operation performed by Robert F. Spetzler at the Barrow Neurological Institute in Phoenix, Arizona. Reynolds was under close medical monitoring during the entire operation. During part of the operation she had no brain-wave activity and no blood flowing in her brain, which rendered her clinically dead. She claimed to have made several observations during the procedure which medical personnel reported to be accurate.

Autobiographical memory (AM) is a memory system consisting of episodes recollected from an individual's life, based on a combination of episodic and semantic memory. It is thus a type of explicit memory.

Childhood amnesia, also called infantile amnesia, is the inability of adults to retrieve episodic memories before the age of three to four years. It may also refer to the scarcity or fragmentation of memories recollected from early childhood, particularly occurring between the ages of 3 and 6. On average, this fragmented period wanes off at around 4.7 years. Around 5–6 years of age in particular is thought to be when autobiographical memory seems to stabilize and be on par with adults. The development of a cognitive self is also thought by some to have an effect on encoding and storing early memories.

The fading affect bias, more commonly known as FAB, is a psychological phenomenon in which memories associated with negative emotions tend to be forgotten more quickly than those associated with positive emotions. FAB only refers to the feelings one has associated with the memories and not the content of the memories themselves. Early research studied FAB retrospectively, or through personal reflection, which brought about some criticism because retrospective analysis can be affected by subjective retrospective biases. However, new research using non-retrospective recall studies have found evidence for FAB, and the phenomenon has become largely accepted.

Overgeneral autobiographical memory (OGM) is an inability to retrieve specific memories from one's autobiographical memory. Instead, general memories are recalled, such as repeated events or events occurring over broad periods. For example, when asked to recall a happy event, a person who exhibits OGM may say, "when I was on vacation last month" instead of remembering a single incident, such as, "my high school graduation." Research shows a correlation between OGM and certain mental illnesses, such as major depressive disorder (MDD) and posttraumatic stress disorder (PTSD).

Terminal lucidity is an unexpected return of consciousness, mental clarity or memory shortly before death in individuals with severe psychiatric or neurological disorders. It has been reported by physicians since the 19th century. Terminal lucidity is a narrower term than the phenomenon paradoxical lucidity where return of mental clarity can occur anytime. However, as of 2024, terminal lucidity is not considered a medical term and there is no official consensus on the identifying characteristics.
