When we know the reason of dreams, we will naturally be enlightened.
Some dreams are caused by over-sensitivity, which are common in daytime and nighttime. The second is the sense of crisis, that is, the more afraid of what will happen, the more dreams will dream.
It is also caused by personality problems, such as extreme personality and easy to dream more. Some people have too much pressure in life, which leads to poor sleep quality and more dreams.
So many dreams are caused by themselves. The key is to maintain a stable mood, not because of things, not because of things.
