The cage has different meanings depending on what it inside of it. So, if it contains a bird, this dream predicts friendship and love, and shows you know how to enjoy life. On the other hand, if the cage is empty, the image expressed a clear feeling of disillusion and disappointment. If you see yourself caged, it is a sign that the unconscious wants to express its complaints, since you are subjected to heavy repression by the conscious. You have become a very strict judge of yourself and limit your acts and thoughts too much, which prevents you from expressing yourself freely. However, if wild beasts are caged, you have to interpret this dream as the retention of inner conflicts that torment you, in which case this oneiric image has some similarity to the previous (in which you are locked in a cage). If you are put in a cage with wild animals, the dream is warning you that you are in danger of an accident.
One of the reasons why people always get involved in road accidents is that, they are tired while driving, or that they lack sleep. Many people do not realize that their performance can be highly affected by having not enough sleep. Sleep deprivation can affect reaction as well as decision making, not to mention that it could make a person unable to drive well. It goes the same with drunk driving.
Enhance your grades
Most of the kids, ages 10 to 16 are suffering breathing disorder when they sleep. It could be sleep apnea, snoring, and other kinds of interrupted breathing disorders. It's been said that students suffering from such have problems in terms of concentrating and learning, which can surely lead to a functional impairment at their school. Even college students who do not get enough of sleep at night have worse grades. Well, sacrificing sleep in order to meet some sort of deadline can be ideal, but depriving oneself to sleep will surely impair learning, which is not good for students.
