  1. The déjà vu phenomenon is difficult to research and there is little information, evidence or firsthand witnessing of déjà vu, except for the person who spontaneously announces they've just experienced it. Scientists, philosophers, psychologists and paranormal experts have been grappling with the meaning of déjà vu for more than two centuries with little success. Sigmund Freud believed déjà vu is caused by repressed desires or memories. Until lately, however, serious study of déjà vu was avoided because the subject became entrenched in paranormal associations such as alien abductions. Brain imaging technology has placed déjà vu within the study of memory. Research shows that younger people with active imaginations are more likely to experience déjà vu.
