Good Morning, @hadedami and welcome to Mayo Connect.
Without knowing more about you, your physical condition, and what is happening in your life, it is difficult to say what is causing your problem.

One of the most common causes of sudden, unexplained excessive dreaming is stress - our bodies react in many ways to it. Another is medications, particularly antidepressants. This can happen with a new med, a change in dose, or a change in health that causes your body to react differently to the medication.

Here is what Mayo Clinic has to say about excessive dreaming :

Have you spoken to your doctor about the problem?
