The Simple Answer is No
There are many different dream states that you may find yourself in throughout your life i have listed some of the dream states Below.
They are created by ourselves as the reality we want. Dream reality is removed from physical reality as a prearranged series of events in which we play a role. It's like being an actor in a movie. However, there are different variations of ordinary or common dreams which differ due to personal desires or influential substances within the body. For example, if we are using a prescribed drug or medicine due to a certain illness, this might have certain side effects which the body is not accustomed to and when we dream, it may change the entire meaning of an experience. Other ordinary dreams are influenced due to our individual personality or desires.
Although a nightmare might shake us up, they should not be taken literally, as they may only be warning for a potential event. However, nightmares may also occur due to a preoccupation with solving a problem or if experiencing the side effects of a medicine we are taking. Certain foods can also trigger nightmares. Some bad experiences we had in the past could also be recalled by our subconscious mind in the present through nightmares. Nightmares are very different from reincarnation dreams that contain negative experiences.
UNIVERSAL ARCHETYPE DREAMS
Since we all belong to the same Origin, a person may have the same dream as another due to the Universal Consciousness we all share.
A Dream in which you know that you are dreaming is called a 'lucid dream'. It generally happens when you realize during the course of a dream that you are dreaming, perhaps because something strange or unexpected occurs. These types of dreams may reveal personal information as you observe the development of the dream through the expression of your feelings while being aware that you are dreaming. A lucid dream may develop directly or indirectly into an OBE. Sometimes during lucid dreaming we loose concentration for a brief period of time.
SPIRIT GUIDE DREAMS
When we are having an ordinary dream and some of the characters protect us, we are being contacted by our Spirit Guides. Protection may take shape through a helping hand or communication. The Entities in these dreams are in fact our Spirit Guides, which we all have throughout our lifetimes. When communication takes place we don't feel scared or shy as subconsciously we know them from other realities. These dreams differ from mediumship because they start and end as ordinary dreams, and in between we are introduced to Entities wishing to communicate.
ASTRAL PROJECTION OR O.B.E.
When the Astral Body separates itself from the physical self and travels to a particular place or event, the experience is referred to as an Out of Body Experience. OBEs are of many types, such as Interdimensional projection, NDEs and others.
Prophetic dreams or Veridical dreams - these dreams have a definite impact on us as we remember them quite vividly. They represent future events that are being foreseen or foretold.
Telepathic dreams - the dreamer receives information from another person, either living or dead, but pertaining to the present. The message may come from a distance.
Reincarnation dreams or past life dreams are dreams in which an individual sees himself/herself going through actions or places with which he or she is not familiar in present existence. These dreams differ from mystical experiences as they are normally in black and white. Mystical experiences of past lifetimes are a form of OBE and may be triggered through a form of trance or hypnotic regression. What we experience is very real.
Clairvoyant dreams - these dreams allows the dreamer to perceive things beyond the natural range of senses which trigger extrasensory perception (ESP). In other words the dream creates a keen intuitive understanding of places or events related or unrelated to the person.
