reactivation of a pastmemory due to similar circumstances in the present approximating circumstances of the past. For example, if a person had a memory, or mental image picture, of a drug "trip" which included a hallucination of swirling colors, the entirety of that mental image picture could be reactivated and brought into play by the person seeing something in present time which approximated the swirling colors in his memory. With this mental image picture in restimulation, the person could experience the same sensations as he did when he originally took the drug.
