Nearly four years before school shooter Nikolas Cruz gunned down 17 students and educators at a Parkland high school, he confided in a therapist that he saw himself in a dream drenched in human blood.

A May 3, 2014, notation in a Broward County schools psychiatric file said Cruz “reported [a dream] last week of him killing people and covered in blood. He smiled and told the therapist that sometimes he says things for shock value.”
