If someone dreams about something it can become a reality. The total reality is not dominated by any one dream, it is dominated the effects of all minds and spirits.
However, a dream can dominate one person's reality if it is a persistent and recurring dream.
Dreams can sometimes be the answer to a question. Often there is no apparent meaning. Sometimes young children dream of frightening things that do not really exist.
When someone thinks of making things better in some way it is often called a dream. But taking action can bring it into reality. If other people think your ideas are impossible to achieve, they will call you a dreamer.
But if you think about washing the dog, dream about it while sleeping, and then do it the next day, your dream has helped form the new reality, a clean dog.
You can dream about things that already happened, a dream based on past reality.
A few people can have fantastic dreams and still be normal when they are awake. Others may day dream about another place, other people, or other activities even when in the classroom.
If you try to force your dreams toward harm for others, that is a first step to going crazy.
People can seek evil, dream about it, and bring it to pass.
An occasional bad thought is something everyone has, like running a cement truck over someone whom you do not like. All normal people know not to act out such a thought.
The few who do not will end up in prison or in an insane asylum.
Watching too many horror movies can cause bad dreams.
I dream far less than most people, probably because I am far more science oriented.
However, sometimes I have put myself to sleep thinking about God, the angels, or other higher things.
I have also had lots and lots of questions all through life, far more than the average.
If the question is extremely difficult, often the only person to ask is God.
