Dissociative Identity Disorder (DID) involves a significant disruption in a person’s sense of identity and continuity of self. A person may experience two or more distinct identity states or ways of experiencing themselves, together with memory gaps that cannot be explained by ordinary forgetfulness. These experiences are involuntary and may affect relationships, daily functioning, emotional regulation, and a person’s understanding of their own experiences.

Symptoms:

• Experiencing distinct identity states or different ways of feeling and behaving

• Significant gaps in memory for everyday events or personal information

• Feeling as though certain thoughts, emotions, actions, or memories do not belong to oneself

• Finding evidence of actions, conversations, purchases, or activities one does not remember

• Experiencing changes in voice, posture, preferences, abilities, or mannerisms

• Feeling uncertain or confused about one’s identity and sense of self

• Losing periods of time or being unable to recall how one arrived somewhere

• Experiencing significant distress or difficulty functioning because of these symptoms

Depersonalization involves feeling detached from oneself, one’s body, thoughts, or emotions. A person may feel as though they are observing themselves from outside their body or moving through life without feeling fully present.

Symptoms:

• Feeling disconnected from one’s body, thoughts, feelings, or emotions

• Feeling as though one is watching oneself from outside the body

• Feeling emotionally numb, unreal, robotic, or unlike oneself

• Difficulty recognizing or connecting with one’s reflection

• Feeling detached from one’s actions or unable to control them fully

Derealization involves feeling disconnected from one’s surroundings. Familiar people, places, or situations may feel strange, distant, dreamlike, artificial, or unreal.

Symptoms:

• Feeling as though the world is foggy, dreamlike, or unreal

• Familiar surroundings suddenly feeling unfamiliar or distant

• Feeling separated from the environment by a wall, fog, or barrier

• Changes in how time, distance, sound, colour, or size are perceived

• Difficulty feeling emotionally connected to people or surroundings

Dissociative amnesia involves difficulty remembering important personal information or experiences that would not ordinarily be forgotten. Memory gaps may relate to stressful, overwhelming, or traumatic events.

Symptoms:

• Gaps in memory for certain events or periods of time

• Difficulty recalling parts of stressful or traumatic experiences

• Finding evidence of conversations or actions one does not remember

• Losing track of how one arrived somewhere or completed a task

• Feeling confused or distressed about missing memories

Emotional detachment may involve feeling cut off from emotions, relationships, or experiences. Although this can provide temporary protection from distress, it may also make it difficult to experience closeness, enjoyment, or emotional connection.

Symptoms:

• Feeling emotionally numb, empty, or shut down

• Difficulty identifying or expressing emotions

• Feeling disconnected from loved ones or relationships

• Limited emotional response to significant events

• Difficulty experiencing pleasure, affection, grief, or excitement

Some individuals experience uncertainty or disconnection regarding who they are, what they feel, or how different parts of their personality fit together. Their sense of identity may shift depending on the situation or relationship.

Symptoms:

• Feeling unsure of one’s identity, preferences, values, or needs

• Feeling like a different person in different situations

• Experiencing internal conflict between different parts of oneself

• Feeling unfamiliar with one’s own actions, emotions, or personal history

• Difficulty developing a stable and continuous sense of self

Dissociation can become more noticeable during periods of intense stress, interpersonal conflict, reminders of trauma, or emotional overwhelm. A person may mentally “check out” when an experience feels too difficult to process.

Symptoms:

• Feeling blank, frozen, distant, or mentally absent during stressful situations

• Difficulty following conversations when emotionally overwhelmed

• Losing awareness of time or one’s surroundings

• Feeling disconnected during conflict, intimacy, or trauma reminders

• Returning to awareness without clearly remembering what occurred
