My informant told me about a time when he was younger, maybe thirteen, and he had a dream about his teeth falling out. In the dream, his teeth began to feel loose and when he touched them they started to all fall out. He remembers being mortified and having a great sense of anxiety; the dream felt very real. When he woke up, he told his grandma, who lived with him. She got angry at him and told him the dream meant he had been telling lies; this was common knowledge in China. He tried to tell her he hadn’t been, but she wouldn’t believe him. His parents didn’t think much of the dream, though, and didn’t think their son had been telling lies.
He said he remembers the incident because the dream felt very real and it had disturbed him. He’d also been very upset to have his grandma angry at him when he felt he hadn’t done anything wrong. I could even see him become uncomfortable as he remembered the event.
I think it’s interesting to see that while his grandma put a lot of stock in this folk belief, his parents, the next generation, did not. This could reflect a changing attitude in the world and show how more recent generations are more apt to side with science and logic rather than trust old folk beliefs and superstitions. I also think it’s interesting to see that losing teeth became symbolic of telling lies, as if the lies had been so caustic that when they exited the mouth, they caused the teeth to fall out. Or maybe losing teeth in the dream was almost like a punishment for lying. I’ve heard the more modern belief that losing teeth in a dream represents a lack of confidence or feeling of insecurity. Because we use teeth to forcefully chew our food, they represent power, and seeing them fall out could reflect a sense that we have lost power in our lives. Another interpretation I’ve heard of the dream is that it indicates a family member will die, though I don’t know how that necessarily relates to teeth falling out, except maybe because people lose their teeth when they grow old and approach death.
