This is a case study of art therapy applied on a 7 year old, elementary school boy who used to have nightmares. In the study, it claims that the art therapy helps the child become free from fear and anxiety he has experienced in his nightmares in which ghosts and monsters appear and kill him. This program consists of 14 sessions, each of which takes about 60-80 minutes once a week. In order to prove the effect of art therapy, 3 pretests--L TM; Landscape Montage Technique; PITR(Person-In-The-Rain)--are perfonned to examine the child\'s cognition, stress, desire, and family structure that may have caused his nightmares. After practicing art therapy, the same tests are performed again as post tests. The results show that this case study proves to be very effective for a child who is suffering from nightmares, in a way that the art therapy helps the child not only escape and Ieel Iree from nightmares but become himself much interested in art.
