Water is a very important symbol to humanity that means a lot of different things to many different people. In some cases water can represent emotions and strength. It can also represent the fluidity of life and the experiences that we all have and share together. Water can also represent purity and it can show just how you navigate through life. Sometimes water can be a way for humans to return to nature too. You try your hardest to integrate into modern society but sometimes you just need to take some time to return to your roots.
Because of how connected humans are to water, because of the fact that humans are made out of water and because water is such an important symbol and commodity across all cultures, it only makes sense that humans would sometimes dream about water. If you have a dream in which you see deep water it can mean that you are worried about the way you have been receiving emotions recently. You think that you need to go to out and express yourself more clearly. To dream that you are outside of that deep water or looking into it means that you are deeply concerned about an issue but that you have spent very little time considering it deeply or really thinking about it. To dream that you are submerged in deep water or heading to the bottom of deep water means that you are really diving deep into an issue that is important to you and thinking about it from all angles. It can also mean that you are trying your best to understand your views on a subject that you might have been educated in but never really thought about until just recently.
If you have a dream in which you see deep dark or blue water it means that your life is incredibly pure but also fraught with a lot of different thoughts. A truly clear water pool would mean that you have nothing to worry about whatsoever. You have no reason to be deeply concerned with anything and no reason to seriously be worried about anything in your life. If you see deep blue water it means that while your life may still have some issues and while you are busy with new thoughts every day, you will work through them because of your endless and relentless ability to adapt to what goes on around you and to new lines of thought that challenge you and make you feel a lot more used to what is going on around you even though it may all seem a lot harder to work with. Dark water means your life is always fraught with new things and you can't exactly see what's coming ahead but your level headed attitude and your ability to stay in touch with your true emotions will carry you through the roughest of these times. Congratulations for mastering yourself, it is something that most people cannot do.
