Types of hallucination

There are two main types of hallucination that people with Charles Bonnet syndrome tendto experience. They may see:

  • simple repeated patterns
  • complex images of people, objects or landscapes

Simple repeated patterns can take the form of grids, shapes or lines, which can appear inbright or vivid colours. The patterns may lay across or cover everything the person sees.

More complexhallucinations can involve people, places,animals and insects. Most people don't see hallucinations of people they know or past events they've experienced.

The hallucinations aren't usually unpleasant or threatening, but they may beslightlyfrightening when first experienced. The can sometimes occur out of the blue, and can last fora few minutes or several hours. They may be moving or static.
