In dreams, a child can represent your most juvenile part, and your potential. Maybe, you recognize in him the hopes and ideals you had in the past. Arguing with him indicates that something in you is rebelling. If, in the dream, you get along with them or there is a reconciliation, it indicates that you are giving up due to certain demands or conditions. It may also deal with your own child and the meaning would be literal. To dream of a beautiful daughter denotes interesting friends; an ugly one, strange devotion. A son, on the other hand, denotes work.
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.
Reading in dream
Sometimes you will not be able to differentiate lucid dream. If you want to be sure, try reading a simple sentence, if you are able to read then you are in wakeful stage if not you are in lucid dreaming. Studies show that you cannot read while dreaming or you will not find the repeated sentences one more time.
