*2.3.6 Visualization*

Both trance and suggestions can be induced using the visualization technique. For instance, a subject can be asked to recall a room he is familiar with, to imaging every detail in the room such as the windows, the floor, the light, the wall, the painting etc. Afterward, the subject then moves into a room he is less familiar with. As the subject struggles to recall the exact details, his mind is open to suggestion. Visualization can be used to recall positive memories and positive images and experiences (wedding, birthday graduation) to change one's perception of a negative image [25].
