Nobody likes being dizzy because it keeps them in a daze and makes all of their movements harder to make. On top of that, not only does it stagger their movement but it also confuses the brain and makes it more difficult to perform even the simplest of operations. If you have a dream in which you are dizzy this can be quite annoying, but it usually has a concrete meaning.
If you have a dream that you are dizzy then this usually occurs because things in your life are passing by way too fast. There is too much going on for you lately and you are starting to get confused by how active everything is and how strange it is that there is still so much going on. If you have a dream that you are dizzy then it means that you have just been pulled from opposite sides and are not sure where you should be going anymore. This is the way life works sometimes but it does not mean that you have to like it.
Also, believe it or not one of the reasons you might be dreaming of being dizzy is because you actually are dizzy or should be dizzy in real life. This can come due to motion sickness. Perhaps you fell to sleep in the backseat of a car that is suddenly going on a winding path. This is kind of unlikely but a possibility. The more likely possibility is that you are dizzy in real life because you are actually sick which can lead to feelings of dizziness. However you got there, the reason you are dreaming of being dizzy is because you are actually dizzy in real life.
