Can you explain my dreams?

I have the most frustrating dreams ever! One time i dreamed about being superman but i couldnt fly. I felt like i had the power to and i keep on trying to fly but i always fall. Sometimes i get to a certain height but i fall again. Other dreams are exactly like this. For example, I have a gun and im celebrated as one of the best shooters out there. But when i try to shoot something I dont have ammo. They are very frustrating. I feel like i have the ability to do something but i just cant do it!
