Delusions are unshakeable beliefs which are obviously untrue. For example, an ill person might strongly believe that there is a plot to harm them that they are being spied on through the TV or being taken over by aliens. Thought disorder is a serious disturbance in thinking clearly. It is more than just feeling a bit muddled or confused at times. Other people may find the person hard to understand because their sentences don t make sense and their ideas are all jumbled up.
Hallucinations are when someone sees, hears, smells or feels something that isn t really there.
The most common hallucination that people have is hearing voices. In schizophrenia, hallucinations happen often and are believed to be totally real by the person having them. This can be frightening and can make them believe that they are being watched or picked on. People who are having these experiences may act strangely. For example, they may talk or laugh to themselves as if talking to somebody that you can t see.
