For human beings a dream is an experience of images, sounds and other sensations like fear, distress, hope and so on during a period of sleep.
Dreams can be a distortion of waking experiences or of expectations not realized in the waking state and
strong emotional sensations can occur involuntarily in the mind during sleep.
In some cases, inspiration can occur while dreaming, resulting in acts of creativity once in the wakeful state.
In modern times dreams have been seen as a connection to the unconscious mind and another theory suggests that dreaming refreshes the mind, much like clearing clutter from one's computer.
Some people say that they never dream, but the truth is everyone dreams every night, the recall being significant.
Different levels of sleep do occur with dreams being most vivid and remembered during what is known as REM sleep, namely rapid eye movement, being movement of the eyes beneath the lids. At this level most dreaming occurs.
DIFFERENT TYPES OF DREAMS
These are far more intense than bad dreams, causing emotions like anxiety and outright fear stuck in slow motion, having unpleasant associations with the dreamer unable to solve conflicts and unresolved issues in life. Contributing factors could be medication, stress and anxiety and eating before sleep, triggering an increase in metabolism and brain activity. Nightmares are more likely to be more reoccurring than milder dreams.
During sleep it is natural for the body to paralyze muscles this being a mechanism to halt any "movement" in a dream, which may cause the physical body to move. On awaking the sleeper can feel paralyzed, a quite daunting sensation, usually short lived.
These dreams can have a positive effect on the psyche as during sleep they compensate for unfulfilled desires.
These dreams are thought by many to predict future events, but mainstream science does not generally accept ESP [Extra sensory perception]
Dreams of this variety might include a variety of events, like motor car accidents, airplane crashes and sinking ships.
It may be mentioned that in previous eras many swore blind that the sinking of the Titanic was predicted! Usually nothing comes of these events and the outcome is pure co-incidence.
Compared with the above mentioned a lucid dream is best explained when one is aware that one is dreaming, which can range from very faint recognition of something beyond what has been experienced in waking life. It may border on Deja-vu [French for already seen] arousing a strong sense of familiarity.
On a more "down-to-earth level" one may dream of pleasurable experiences like a visit to a health spa or a gift of luxurious Matsimela products! If this occurs, head straight to your nearest store and indulge in pure pleasure!
