Claims of sighting, visitation, and contact with extraterrestrial or paranormal-connected unidentified flying objects (UFOs) has been the subject of extensive medical and psychological research. While some research indicates psychopathological origins for claims of such experiences, other studies point to the likelihood so-called "experiencers" simply have overactive imaginations.
Treatment of persons reporting a belief in contact with UFOs or non-human intelligences has involved antipsychotic medication, psychotherapy, and lifestyle changes.
