For the last 3 months our three-year-old has been voicing concerns about things she thinks about before she falls asleep at night. We didn't really take her seriously until she finally said,

"I need you to know something. Always when I go to sleep I see pictures that are so real in my eyes, and it is like I am living in these scary pictures about witches, ghost-es, monsters,..."

She was so concerned. We told her to try to think about pictures of Disneyland in her eyes.
