Scientists have long known that children who are exposed to rich and varied environmental stimuli at an early age tend to develop a well-rounded knowledge base. They not only excel in math and language, but also in sports and the arts.
One of my favorite things to use hypnosis for is synesthesia. Synesthesia is a perceptual condition of mixed sensations whereby stimulus in one sense (e.g., hearing) involuntarily elicits a sensation in another modality (e.g. vision). For example, you look at a tree and you feel warm, or you walk on the beach bare-footed and smell onions.
Rather than me explain it, watch David Eagleman talk about it on his video,
Seeing Sound, Tasting Color: Synesthesia
Through hypnosis, the experience of synesthesia can be triggered in people who have never experienced it. My belief is that it helps a person widen their view of reality and, thus, enhances creativity.
