New to the topic of mental health? Confused by the terms you’re seeing? Don’t know the difference between “psychosis” and “delusion”? No worries! Press Ctrl-f or ⌘-f to search for the term you are looking for. The description of said terms is straight to the point, but not concise.

If you cannot find it, leave a comment and we’ll add it in. We try to avoid fancy terms like “dissociation” without explanation, but we may forget to do so within our posts.

Alternatively, you may browse by letter:


Auditory hallucination: Things an individual hears that aren’t there.

American Psychiatric Association (APA): The APA is the largest organisation of psychologists in the United States. They also publish the Diagnostic Statistical Manual, used for the diagnosis of mental illness.


Cognitive Behavioural Therapy (CBT): A form of psychotherapy that is widely used today. It works by doing things like identifying irrational thoughts (e.g. I have no talent) and changing them (e.g. I am not musically talented, but I have other talents such as cooking). Irrational thoughts are not delusions.

Conscious: Thoughts and thought processes you have that you are aware of.


Delusions: False beliefs that remain even when it has no proof, or has been proven to be false. There are many different forms of delusions, such as grandiosity (I am the king) and persecutory (the cleaner is a spy sent by the government to track me); not to be confused with hallucinations.  Also see: psychosis, hallucinations, delusions. 

Diagnostic Statistical Manual (DSM): It is a widely used manual for diagnosing mental illness; remember not to diagnose yourself or others if you are not professionally trained.

Dissociation: Often related to dissociative identity disorder (DID; previously known as multiple personality disorder), a state of dissociation is the separation of a person’s mind, emotions, and actions. It has been described as an out-of-body experience.


Hallucinations: Things that a person sees (visual hallucination), hears (auditory), feels (sensory), or smells (olfactory) that are not there.  Also see: psychosis, hallucinations, delusions


Psychosis: Someone with psychosis has lost contact with reality; they experience things that are not real. Also see: hallucinations, delusions

Psychotherapy: A form of treatment (“talk therapy”). There are many psychotherapy kinds, such as cognitive behavioural therapy.


Schema therapy: A form of treatment that combines a few different therapies  Also see:Cognitive Behavioural Therapy


Unconscious: The unconscious mind refers to thought processes in our head that we are not aware of (e.g. when we base people on stereotypes without realising).
