False memories, memories of events that never actually happened, can be just as upsetting, just as emotional as memories for real events. Other investigators have examined the way a memory feels, relying on the "remember/know" distinction. It turns out that a feeling of "remembering" is more likely with correct memories than with false memories. False memories often arrive with only a general sense of familiarity and no recollection of a particular episode. But there are numerous exceptions to this pattern. The subjective distinction between knowing and remembering, cannot serve as a reliable means of distinguishing correct memories from false ones.
