No. "Precognitive" means fore-knowing, or knowing something ahead of time. Precognitive dreams supposedly predict the future. Hallucinations are different in that dreams occur during one's sleep, while hallucinations occur when one is awake, often when one is feverish or otherwise impaired.

Schizophrenic hallucinations can be either. However, most schizophrenics report predominantly or entirely auditory hallucinations.
Symptoms of hallucinations include seeing, smelling, or hearing things that are not present in the environment. Typical hallucinations involve seeing or hearing, but neither the eyes or ears have any physical problem. Instead, brain changes trigger hallucinations. Schizophrenics often experience hallucinations and many medications or street drugs can trigger hallucinations.
Yes.In severe cases of type 1 Bipolar, manias and mixed states (and even in rarer cases depressions) may be accompanied by psychotic features. Though delusions are the most common psychotic feature, hallucinations may be present.Generally, gustatory and olfactory hallucinations (noticing non-existent tastes and smells) are most common, next comes auditory hallucinations (typically unstructured sounds are more common than voices, but voices occur as well) followed by visual hallucinations, tactile hallucinations (touch) seem to be rare.-----------------------------------------------------------------------------------------------------------------------------------------------I have personally had auditory hallucinations (always voices with identifiable "unique personalities" and almost always originating from a direction above and to the right of me, probably more than 10 different voices) and olfactory hallucinations (always a burnt electric motor "smoke & ozone" smell), no visual or other hallucinations.
