A psychotic spectrum
Symptoms differ from person to person. And for each person they can vary from week to week, or even moment to moment. That is why we speak of a psychotic spectrum.
A psychosis can be short-term and of a one-off nature, or return periodically. In both cases, it can be a very shocking and disturbing experience.
When people suffer from psychoses for a longer period of time, they are diagnosed with long-term psychosis, which used to be called schizophrenia. In contrast to what most people think, this does not mean you have a split personality. However, during psychotic episodes one loses contact with reality to a greater or lesser extent.
