These advanced Alien groups can simulate Schizophrenia and hallucinations VERY easily. They simply Teleport a person around you to a duplicate city, have a Clone of that person make threats towards a Target and then move the original person back to that city. 

Meaning, the person who received the threat now appears to be a 'Schizo' because they are accusing an innocent person around of making threats towards them. It appears to be a 'hallucination' when the threat was very real. This is how advanced Alien groups (and Humans they have shared technology with) manipulate Targets...
