Your scream may trigger your mind into a Mind Enslavement trance. This mind enslavement trance possibility passed from generation to generation for survival purposes. On the other hand, apparent respectful people as hidden bullies, can use it to mind enslave his victims for his own Anti Civilized purposes.
Example: Father screams JUDEEE STOP, to his 1.5 year-old daughter. His daughter was about to run into the street in front of an onrushing car. His daughter stops short and her life was saved. (This happened to me personally.)
Another Example: Apparently respectful person wins over his victim and suddenly screams at the potential victim that he is a bad person and does not stop his contemptuous remarks. This potential victim identifies with this Anti Civilized person due to his mind alleviating run away anxiety, and his mind can’t find its way back to his former Civilized mind state. This potential victim is now victimized. The potential victim would not have fallen into this mind trap if he had been protected by the Safeguarded Life Oriented Way in Safeguarded Countermeasures To Counter Mind Enslavement Systems, 2.2 Safeguarded Life Oriented Way.
