Yes, a person can be delusional about something that isn't real. Delusions are false beliefs that persist despite clear evidence to the contrary and are not culturally or religiously accepted. These beliefs are not based on reality or supported by rational reasoning. Delusions can occur in various psychiatric and psychological disorders, such as schizophrenia, delusional disorder, bipolar disorder, and sometimes in severe cases of depression.
Delusions can take various forms, including:
Paranoid delusions: Believing that others are plotting against or persecuting the individual, even when there is no evidence to support such beliefs.
Grandiose delusions: Holding an inflated sense of self-importance, talent, or identity, often believing they have exceptional abilities or are someone of great significance (e.g., a famous historical figure or religious deity).
Somatic delusions: Having false beliefs about one's body, health, or physical appearance, such as thinking one has a serious illness despite medical evidence to the contrary.
Delusions of reference: Interpreting neutral events or everyday occurrences as being directly related to oneself, even though there is no logical connection.
Thought broadcasting or thought insertion: Believing that one's thoughts are being broadcasted to others or that external forces are inserting thoughts into one's mind.
Delusions are different from ordinary beliefs in that they are rigid, fixed, and resistant to change, regardless of evidence presented to the contrary. Delusional individuals often have impaired insight, meaning they are unable to recognize that their beliefs are not based on reality.
It's important to note that delusions are a symptom of an underlying mental health condition, and individuals experiencing delusions require professional evaluation and treatment. Delusional beliefs can cause significant distress, impair daily functioning, and lead to behaviors that may be harmful to oneself or others. Treatments may include psychotherapy, medication, or a combination of both, depending on the underlying condition and its severity.
