Delusion vs Hallucination
For a lot of people the distinction between hallucinations and delusions can be very confusing and scary. However, delusions and hallucinations are different, they are not to be used interchangeably. Hallucinations are characterized as false or distorted sensory experiences that appear to be veridical perceptions. Veridical perceptions are defined as those that are correct comprehension of what is authentic and real. These sensory impressions are generated by the mind rather than by any external stimuli, and may be seen, heard, felt, and even smelled or tasted. Sensory impressions involved in hallucinations have a “real base”, as the mind can create a “lifelike” experience leading the individual to believe he or she is really hearing, tasting, smelling, etc., what they are hearing, tasting, smelling, etc.
Unlike, hallucinations a delusion is a fixed false belief, often, used in everyday language to describe a belief that is either false, whimsical, or derived from deception. Delusions are typically false beliefs based on incorrect inference about external reality which is firmly sustained despite what almost everybody else believes and despite what constitutes incontrovertible and obvious proof or evidence to the contrary.
Delusions are often associated with mental illness, specifically, mood and personality disorders such as bipolar disorder, schizophrenia, delusional disorder, schizoaffective disorder, etc. Notably, persons struggling with delusional disorders may experience complex delusions which often fall into the following categories:
