Gaslighting is defined by wikipedia as 'a form of psychological manipulation in which a person seeks to sow seeds of doubt in a targeted individual or in members of a targeted group, making them question their own memory, perception, and sanity. Using persistent denial, misdirection, contradiction, and lying, gaslighting involves attempts to destabilize the victim and delegitimize the victim's belief.'

This was untrue: the 'carer'was merely playing these noises from an app on heri phone.s
