有study研究過
佢地覺得有兩大可能:
1. 實際牙齒問題(如夢中磨牙既sensation引致)
2. 心理壓力,係夢中以甩牙比喻形式呈現出中
The authors suggested two potential hypotheses—that teeth dreams are related to actual dental distress such as teeth grinding during sleep; or that teeth dreams are more metaphorically related to factors of psychological distress.
結果似乎係甩牙夢同牙齒問題有關係,但唔一定同磨牙有關
btw有關係 唔等於 有因果關係
In general, the study shows that teeth dreams are significantly associated with dental irritation and that this relationship seems to be relatively specific.
