This piece shows the defining symptom in those who have Inattentive ADHD. It goes by many names: daydreaming, zoning out, losing focus, staring into space. People experiencing this symptom often lose all sense of what is going on around them and are transported to another place entirely, thinking about thing unrelated to their current situation. At times the state can be taken so far as the person thinking about absolutely nothing at all, not realizing this until they snap out of it.
