The water dreams most often can be caused by internal and external stimulus. Notwithstanding, prophetic message about a pregnancy can be encoded in a water dream too. Thus symbolic significance of water is based on psychological and physiological functions of human body, and is a tool to decipher hidden meaning of your dream.
For everyone, as internal stimulus is a full bladder. Unavoidable need to use a toilet for peeing makes a dream of water. Your subconscious mind follows physical state of your body and calls you to wake up by giving you a feeling of wetness. Thus it can be achieved by dreaming about swimming in ocean, sea, river or even being in a rain. Any kind of a liquid that touches your body, especially if you are sinking in it, may remind about a time for urination.
For all, a shortage of liquids in a body can be a cause of drinking water dream. This physical dependency is the meaning of a dream and it is represented by any kind of giving or taking water, like fetching it from a well or a tap. An additional need for energy is another meaning, but only if drinking sweet drinks in a dream. Drowning dream can happen because of an excessive consumption of liquids. See full bladder explanation above. All these causes are also internal stimulus, which works as an alert to reassess waking life habits.
For everybody, the Full Moon is a cause of dreams about waves and tides, currents and streams or torrents, floods and waterfalls – or any other movement, the rise and the fall, of water. This meaning comes from the Full Moon influence on the physical World, where the Moon and the Sun and the rotation of the Earth combined together exert the gravitational forces to make water levels changes. Thus bodily liquids are being affected as well. It prompts subconscious mind to recreate water movement, like flooding or waves of ocean or sea, in a dream. The Full Moon and its activity alone is external stimulus, but effect of it on physical body creates internal stimulus. This combined power is affecting all beings.
For a woman, various physical changes brought by fluctuations of liquids before and during the period are a cause for water dreams to occur. It is an internal stimulus. In case of sudden start of bleeding during a sleep, this cause becomes external, as a blood is sensed externally. Thus dreaming of going deep in water, like falling or diving, and suffocating may occur.
For a woman, an ovulation is a reason of floating or walking on water in a dream. It notes that you are prepared to start a new life. Also, dreaming of swimming in deep waters and not feeling shortage of air may represent a release of an ovum. This is internal stimulus. Additionally, same meaning of being fertile is indicated by fishing or seeing fishes in clear water. This fertility knowledge is based on physiological and psychological cooperation in human body, thus it used as a ground for clairvoyance. And symbolic significance of fish in water is always associated with pregnancy.
For a woman, during a pregnancy dreaming of water is usual. An internal stimulus is an amniotic fluid inside a sac within belly where a foetus resides. Thus the movements of embryo increase frequency of water dreams. If foetus moves or water breaks while sleeping, before it happens or during the process, a mind can invoke an image of storm in a sea or an ocean. Also drowning or choking with water means the same.
For a man, especially for a young adult, most common during adolescence, a pressure in the reproductive organs caused by a seminal fluid can be internal stimulus for a dream about water. A nocturnal emission can invoke the visions about being at beach near calm sea or ocean, lying in a bath, swimming in a river or a lake. A release of a sperm resembles running water from shower. Thus during an ejaculation and an orgasm a dream of taking a shower is usual. In addition, a wet dream, as a cause of physical function, consists not only of water but erotic images too, it can be a nude attractive body floating in an aquatic surroundings.
For a woman is same as for a man, but not so frequent. A nocturnal vaginal wetness and an orgasm can trigger the water dreams. It can be seen as overflowing, turbulent water becomes calm.
