Dream is a motion in our subconsciousness that gives us scenes and acts that may or may not happen into reality. Dream is a way of our mind and soul to express our emotion, feelings, affection and reaction to whatever situation we have in the real life. It is a way also of our brain to reboot from being overused, such as when a computer is rebooted to refresh and function normally. Dreams are normally experiencing by all. Dream is a puzzle to human knowledge because of its questionable significance and origin. Dream and imagination are the same, because these two are only fabrication of our mental capability and ability. Dreams occur only in sleep, thus concerning other people's mortality are sometimes associated with them. Nightmares and bad dreams are frightening children in their sleep, so that they are possibly to be awakened and cannot continue to sleep anymore. Some grown-ups too are experiencing them. Bad dreams are produced, because of watching horror movies, bad memories, miseries and heart-breaks. Nightmare is a very serious one. As it was said a while ago, it is the reason why people cannot be awakened anymore from being sleep, because of severe nightmare that cause human's body to metabolically active, thus this very active metabolic processes while sleeping cause the body be imbalanced and leading to death.
On the other hand, dream is a way to see the future or what might happen in the future. Some people see it as a premonition and omen. Dream can be used to know what, where, who, when and how our life will be in the future up to death. Deja vu or already seen is much associated to dreams that are partially enacted in real life. Dreams as it was discussed in the Bible, it was the dream of the king of Egypt to see what the future may be ahead. Eventually, Joseph son of Jacob can interpret dreams and had come to interpret what the king had dreamed, and the famine and drought were able to be overwhelmed. Therefore, dream was used by God to tell the people what might happen in the future.
Vision is an apparition of someone or something through a dream or in a conscious state. Vision might be a premonition, foretelling of something, omen or something that is to happen. As it was discussed in dreams, vision is like what is up to dream. The difference is that vision is more general to use than dream which is more specific when describe.
