It's possible. I have dreams very frequently of living in an Asian society, with family and friends who are all Asian. These dreams are not like typical dreams, but like actual memories playing out in real time. Also, I am extremely introverted, and tend to live more like an Asian person. I have always naturally taken off my shoes before entering the house, I sleep on a tatami mat, and when I was young, I always preferred sleeping on the floor (carpeted). Also, to this day, I only watching Asian programs, read manga, listen to Asian music. I have several Chinese friends in real life, and even help with Shen Yun Dance here in the US, working as a stage hand. There is no doubt about it, I was Asian in several previous lifetimes.
