I think you have above normal visualization abilities and photographic memory. Most of people don’t have these skills.
But in my opinion, you don’t use them correctly : it’s probably all your daydreaming which makes you feel depleted of energy. You have to control your visions and not be controlled by them ; to choose the time when you want to visualize and not be lost in random thoughts.
The best would be that these skills were used in a more creative way. Why not to use them in drawing and painting ? A lot of painters would be jealous of such skills. If you don’t like art, they can also be useful in meditation. The important thing is that you volontarily choose when and what you want to visualize. In this way, your energy would be channeled and not lost.
Of course, you can use it in LD development too. Pedro explained a technique (Visualization Induced Lucid Dreaming or VILD) which you can easily master with your skills.
