Electronic harassment is the purported use of electromagnetic waves to harass, terrorize or Mind Control a victim. Psychologists have identified evidence of auditory hallucinations, delusional disorders or other mental illnesses in online communities supporting those who claim to be targeted.Individuals suffering from auditory hallucinations, delusional disorders or other mental illness have claimed that government agents make use of electric fields, microwaves (such as the microwave auditory effect) and radar to transmit sounds and thoughts into their heads, referring to technology that they say can achieve this as "voice to skull" or "V2K" after an obsolete military designation.
In the US, there are people who hear voices in their heads and claim the government is using "psychotronic torture" Mind Control against them, and who campaign to stop the use of alleged psychotronic and other mind control weapons. These campaigns have received some support from public figures, including former U.S. Congressman Dennis Kucinich and former Missouri State Representative Jim Guest. Yale psychiatry professor Ralph Hoffman notes that people often ascribe voices in their heads to external sources such as government harassment, God, and dead relatives, and it can be difficult to persuade them that their belief in an external influence is delusional. Other experts compare these stories to accounts of alien abductions.
