I went to this website and it shows tons of research done on daydreaming. One that caught my attention is Singer & Antrobus which in one study done 579 college students revealed that if the student is thinking positive the daydream is vivid, if guilty the daydream is dysphoric or dissatisfactic, and if anxious the daydream is distractible.
