About the screaming of TV: I heard, and as a child, and still (I am 26), if I miraculously encounter the old TV. And the ugly scream "ultrasonic scary pests" I hear. :) And no one dragged me to the psychiatrist - my dad, Ph.D., a Ph.D., a researcher, explained what a whistle it was. An appropriate psychiatrist should have done the same.
By the way, dad-physic is sometimes scary. For the night, I was not reading stories about the Red Hat, but told about the structure of the atom, how electricity works and what an atomic bomb is. It provided me with nightmares for my whole childhood. This is honestly, instead of nightmares about Baba Yaga. and :)
