In order to distinguish and classify the different kinds of dreams in which everyone has an experience they may be divided into four variations. Nearly all dreams may be classified under this heading: 1. Physical Stimulus. 2. Subconscious memory. 3. Telepathy. 4. The Actual Astral experience of the Ego or Soul in the Astral region. Physical Stimulus may be the direct cause of impressing certain ideas on the physical brain which may appear to be a reality. The falling of a book, picture or any article in the room may cause the sleeper to dream of firearms; a soldier may dream of a battlefield; a sensitive female may dream it is a burglar; a person who throws the bed clothes off him on a cold night may dream of snow and ice; the continual dropping of water from a faucet in the room of the sleeper has been the direct cause of a friend of mine dreaming of a passenger train; the steady tramping of footsteps overhead may be the cause of dreaming of thunder storms, etc. We must also take into consideration the physical and mental environments of the sleeper. THE SUBCONSCIOUS MEMORY The subconscious memory may be the direct cause of certain dreams. When the mind is centered on certain things, the sleeper goes over his life again and again in phantom fashion. He lives over the experiences of his daily life. Very often the ego enlightens the sleeper of some material thing for his own benefit, which he may use advantageously in his waking state, but as he generally looks at the phenomena of dreams as an hallucination of the brain, he allows many a golden opportunity to slip through his fingers because the materialist's brain cannot grasp things of the spirit. All the knowledge and rubbish of our past lives is stored up in the subconscious mind where it remains in minute form. Memory is only the awakening of the sub-conscious mind, a long and forgotten incident, that has made a deep impression on the mind, is apt to filter through into the conscious state in dreams. In time of illness or when one's vitality is low, the dream picture of the past is apt to play a very prominent part in one's sleep. Childhood and long-forgotten scenes come up frequently and appear as real and genuine as if they had only happened the previous day. They frequently give the dreamer joy or sorrow, according to the stages he passed through. Even action of past lives may come up into the subconscious. Dreams of running around nude without any feeling of shame may be the memory of a previous existence. Falling from a high cliff or trees. Being chased around by some wild animals may be attributed to a primitive past. Dreaming of primitive people, places and things, only takes the dreamer a step nearer the stone age, from whence he came. Instead of looking at these subconscious dreams with horror and dread as some people do they should study them and shape their lives accordingly. TELEPATHIC DREAMS OR THOUGH TRANSFERENCE.
