Psychophobia (from Greek psycho, "mind") is the fear of mind. People with this phobia might have watched movies where innocent people were locked-up and left to rot, forgotten by their family members, and treated like dogs in the mental institution, where they were subjected to very harsh treatments such as electric shock therapy, or some even water immersion therapy and light-deprivation therapy. Others might have family members who are crazy and they are extremely scared that this can also happen to them.
