A delusion of perception is a delusion where an individual has a false belief about what they are experiencing through their senses. This can manifest in various ways, such as believing that they are seeing, hearing, feeling, or smelling things that are not actually present, or interpreting sensory stimuli in an unusual or distorted way.
For example : A person with a delusion of perception may believe that they are hearing voices or seeing people who are not actually there. They may also believe that certain objects or stimuli have special meaning or significance that others cannot perceive.
Delusions can be distressing for the person experiencing them, and can also impact their relationships and daily functioning. Delusions can take many forms.
