You see dollars every single day in your life because you always need to spend money on something. This is the way a consumer culture works, but if you dream about it then it means it is really important to you.
Dollars are an important dream symbol because of how often they are used in the world and what they represent. Dollars can stand for capitalism, they can stand for bondage, and they can stand for both strength and weakness depending on how you interpret them. There are a lot of reasons why you might dream of dollars, dollar bill etc because they are so prevalent. You see them every day. The first rule of dream interpretation is to separate these kinds of dreams from ones with real meaning. As you know, if you see something a lot in real life or come into contact with it a lot then it will be natural for this thing to show up in your dreams. Since most people can't go a day without spending money, if you have a dream about a dollar it might just be because you use this money every day and you are so fixated on it that it is just appearing in your dreams because of that.
On the other hand, dollars do have a dream meaning all their own so if you determine that this is definitely not the reason that you are dreaming of dollars then the most likely reason is that you are thinking of power or you want to acquire power. Power is a highly sought after commodity in this day and age and it is normally attained through money. However, to have this kind of dream might seem a little sinister. After all doesn't it make you sound kind of like a super villain, a little bit? You don't need all that power, no regular man does and to want to achieve that level of power over others seems kind of sickening. You don't want to encroach on them really, do you?
Well, if you have a dream about dollars this could be the reason, because you want this large amount of power and the ability to influence others, of course it could also be because you feel like you need to have a small amount of power or control over small things in just your own life. You don't need to have control over the entire world to have a dream about dollars, this just means that you want to have a little more control over your own life and the way you operate. Even though t he metaphor goes towards big things and grandiose ideas, it can also apply to small local ideas. Perhaps you are being bossed around too much and feel powerless to fight against being told what to do all the time. Nobody likes being told what to do all the time so you are probably one of those that does not like it yourself. If this is the case then you can calm down because all you need to do is just relax and let others know how you feel. They should allow you to have a little more control over your life if you ask nicely. It is your own life after all.
