弗洛伊德在《梦的解析》中说，梦是人们压抑愿望的伪装表现形式（disguised fulfillments of repressed wishes），那么这些常见的噩梦都表达了什么寓意呢做梦梦见自已病的不轻？
All of these dreams mirror fundamental patterns of human behavior. Some believe these dream patterns reflect who we actually are, what we really need and what we believe.
Teeth falling out
Dreams about your teeth can reflect your anxieties about your appearance and how others perceive you. Such dreams may stem from a fear of rejection, embarrassment or feeling unattractive.
As teeth are used to bite, tear and chew, dreams about losing your teeth can stem from a sense of powerlessness which means you may be experiencing self-confidence issues.
Being chased suggests you are running away from something that is causing you fear or anxiety in waking life.
The chaser can also represent an aspect of yourself. Your own feelings of anger, jealousy or fear can manifest itself as the threatening figure.
Unable to find a toilet
Having trouble finding a toilet means you may be finding it difficult to express your needs in a certain situation. It can represent feelings of your personal needs not being met by always putting others first.
You may feel that you are lacking time for personal issues and need more privacy, self-care or self-expression.
Naked in public
Being naked in a dream symbolizes not being able to find yourself, uncertainty, or being wrongly accused.
If you are not the naked person in your dream, but you see a nude person and you are sickened by it, it means you are worried about exposing that person.
Unprepared for an exam
Exam dreams can be so real that we actually wake up convinced we just failed an important test.
At least 1 in every 5 people will experience an exam dream in their lives. Exam dreams are a reflection of your lack of confidence and inability to advance to the next stage in life.
If you fall anywhere and you are overcome by fear, it signifies insecurity and anxiety about a situation.
Enjoying the feeling of falling suggests that you are not afraid of changes.
Dreaming that you are late represents your worry and anxiety about taking a different direction in your life, or that you are trying to get things done but you feel that you are running out of time.
Your unconscious might be telling you that it is never too late to do things you want in your life.
Dreaming about a bug infestation can have two interpretations. One is symbolic of feelings of guilt, minor irritations, or worries that are sneaking up on you.
On the other hand, dreams about bugs are also associated with health problems, which is why many people reported having increasingly common nightmares about bugs during the pandemic.
