True hallucinations are always part of reality

Hallucinations are of two types: true hallucinations and pseudohallucinations. The main difference between them - is that true hallucinations are always "embedded" in the real situation.

For example, if a person sees an alien, that alien walks in his room, interact with objects and casts a shadow. Hallucination communicates with its owner and with the outside world so that hallucinating no doubt about the reality of his vision. Sometimes it looks even more realistic and distinctly than the environment.

Psevdogalyutsinatsii in most cases there are "inside" the body hallucinating. For example, the voice in my head.
