Blood as a dream symbol is very versatile. This is because blood can display such a range of different emotions. Some cultures rejoice blood as it is a life giving substance. It is a formula which allows lives to live. Yet, at the same time, without blood, all of these creatures would die. Blood is a giver and a taker. It is life energy, and at the same time, can become poisoned and polluted. To some people, blood is a very serious symbol for power and family. The dream dictionary usually attempts to take all of these different perspectives on blood together so that it can synthesize out a dream interpretation regarding blood that makes sense to the dreamer.
In the case of blood, as with many other sensitive dream symbols, the meaning of dream about blood is most easily understood through the opinions that the dreamer has on blood. If the dreamer fears the sight of blood and naturally is drawn away from it, then it is likely that the dreamer will not be as receptive to displays of blood in dreams. Therefore, dream meanings of blood for people such as this will usually be negative in some way or related to fear and stress. However if someone views blood as a righteous life giver, and then blood is seen in their dreams, it can mean the exact opposite thing.
If you happen to be losing blood in your dream, or somehow bleeding the dream meaning behind this is that you are feeling exhausted. This probably comes from the phrase being bled dry. This means that you are being pulled to and fro by many different forces and seem to be unable to control the path of your destiny on your own, or fighting for one side.
Other dream interpretations of blood suggest that if you see others bleeding, then this means that you are crying for help. This could be related to you directly or your thoughts on another person. If you have been dealing with stresses recently, and a lot of them have seemed to be too hard for you to handle, then you may be secretly overwhelmed. To see others bleeding in your dreams may suggest that you are undergoing something too intense to handle by yourself and should seek help before tragedy occurs. On the other hand, if you are feeling perfectly fine, then it is possible that you fear for the people that are bleeding in your dreams. Perhaps you think that they are worrying too much and that they might need someone's help. If you are the one having dreams about them, this means that it is only natural that you should be the one to check up on them and see how they are doing. Sometimes dreams can be extremely prophetic experiences, and if you have a dream where someone is in trouble or hurt, it couldn't hurt too much to check up on them. Blood is a serious sign in dreams just as it is in life, and should be taken seriously.
