When I was in high school, I had a recurring(反复的) dream of my teeth falling out. I dreamt about my teeth just about every night for at least three weeks. Sometimes they would fall out one at a time, sometimes all at once. I became terrified that my dreams meant I would actually lose my teeth. Nine years later and about a million trips to the dreams, I still have a full set of teeth, but I’ve learned that when we’re experiencing stress in our lives, it tends to show up in our dreams as well．
Miller says losing teeth indicates burdens that crush your pride. If your teeth are knocked out, you’ll have sudden misfortune． Other explanations for dreams about lost teeth are that the dreamer is feeling powerless in life and may be in a transitional（过度的） period from one situation of life to another. Some experts believe that dreams of losing teeth today show we’re just as insecure and uncertain as we were in childhood．
When I dreamt about my teeth back in high school, I was trying to choose a college— a stressful decision． The dreams resurfaced when college graduation rolled around four years later and I’m sure they’ll start again when I graduate．
A little of stress in our everyday lives is normal. But sometimes it becomes such a regular occurrence in our lives that it influences our dreams and causes us to lose valuable sleep. Understanding our dreams is key to identifying and ending stress in our waking hours and restoring peace to our nighttime hours．
