It is said that all dreams serve a purpose (目的). While there is no agreement among scientists about
why we dream, there are many ideas about the different kinds of dreams we have.
One common kind of dream is the repeating dream, in which the same story is repeated again and again,
often for many months or even years. Some believe these are a sign people have a problem in their life and
once that problem is gone then the dream will stop. Others thinktheyare a way to help people remember
something very important.
Another well-known kind of dream is the nightmare. The pictures and stories in such dreams make
people very afraid and dreamers usually remember them far more clearly than normal dreams. The cause
of such dreams may be seeing somethingterrifyingsuch as a car accident or some deadly snakes. Others
think such dreams may be trying to make a person pay attention to something that is dangerous in their life.
Daydreams happen during wake-time when we forget where we are or what we are doing and find
ourselves in a made-up story or unreal world." We often daydream when we are doing something that is

Instead of waking up, they stay in the dream and are able to control what happens in the dream as if they are
making a movie.
