When we enter a trance our critical mind goes to sleep and we will believe anything. And when we believe something, we think it is real.
Religions trade on trance to perpetuate beliefs neither based on evidence or reason. And the believers act on these beliefs because they think they are real.
So believers in Islam flew two planes into the Twin Towers with all the pride of obedient children. And believers are committing war crimes in Syria as you read, shouting, "God is Great".
