The dream or vision is another aspect of insight. Very often people consider a dream as an automatic action of the mind. But this is not always the case. There is no movement in the mind which is meaningless. Every motion and action has a meaning behind it, every motion is directed towards something either with intention or without. There is no movement, there is no action which is not directed from some source or other.

There are three kinds of dreams.

In the first a person sees his mind working along the same lines as it did during the day, at the same time suggesting the past, present, or future.
Then there is another kind of dream when the mind sees in everything quite the opposite of what is going to happen.
And there is a third type of dream in which one sees something out of the past actually happening, or what is going to happen in the future. This proves that everything on the physical plane is first formed in the inner planes and then registered on the mind in the dream. When one is concentrated one sees the happening more clearly.
There is also a state of dream in which one sees a vision. This happens in a meditative condition. A vision is more communicative, more expressive; it may be a warning which is given for the future, or an incident of the past may be made known. In the vision one can go still further and communicate with the unseen world. But a vision only comes to those who are born with that faculty or have developed that faculty in the mind by becoming fully concentrated.

A dream may be symbolical, and this is the most interesting type of dream. The greater the person, the subtler the symbolism of his dream will be. When someone is gross the symbolism will be gross. The more evolved the person is, the more free, artistic, and subtle the dream will be. For instance, for a poet there will be poetic symbols; and the dream of a musician will have musical symbols; in the dream of the artist there will be symbols of art.

In the realistic dream one actually sees what is going to happen. All that we call accident is only our conception; because we did not know it beforehand we call it accident. This also gives us insight into what we call fate. But there is a plan; it is all planned out and known beforehand to the spirit and to those who know. There are sages who know of their death a year before. There is no such thing as accident. When a person does not know, it means he does not see; but it is there.
