” Hello how are you ? Do you know anything about hypnosis? In a blue suit, white shirt and long umbrella on his wrist, Adonaïs Yankan, 32, accosts a young man on Boulevard de Grenelle (15th century). It’s raining, it’s cold, passers-by are in a hurry or don’t speak French. Redouane, 18, sports bag on his back, stops on the outstretched hand of Ado Pharaon. The hypnotist, who is releasing his book “D’un snap de fingers” this Thursday, with Michel Lafon, explains to the young Moroccan that everyone goes through disconnections.
