My Mindscape Has Returned...

I entered my dreams last night in a lucid state. I was surprised to find myself in a completely black space.
It was not long before I gained full knowledge of where I was... I was in my mindscape.
I was sorely disappointed to find this hollow emptiness, as that would mean that I lost my old mindscape.
I had no choice but to begin my creation anew, but I decided to create something different and not as complex.
My old mindscape took me three years to create, and spanned several solar systems, each created with utmost detail by myself and the beings I created to help me construct several worlds, all based on blueprints I created and using part of my mind to add flexibility to their construction of my universe.
I could at any time during the day enter my mindscape to alter and modify any of the stellar objects where I saw it fit.
When I had ensured the construction of three separate galaxies, each containing more than four hundred Terra class planets and an equal amount of stars orbited by two uninhabitable planetoids, I decided to design lifeforms.
First, I created the human race on planet Terra, or the copy I personally created.
Second, I created a variation of the human race on an utopian planet. the only difference between the two races, was the advancement level, both the technological and genetic. The Ancients, as I named them, were spread over several solar systems, united as an empire.
The third race was genetically human at birth, but would be altered by the governing group based on their position in the civilization. This race was technologically advanced, Having achieved interstellar travel just recently. This race was known as the UEL, meaning United Empire of Lantia, they have just colonized their fiftieth world, most worlds having been terraformed.
After fabricating the background of the three races, I sent the beings I used to create my mindscape to create a fourth race, completely unknown to me. I gave them the frames they were to base the creation on and set them to disappear after the successful construction of the race. The beings were limited by three qualities the race was to be created with. It had to be able to travel through space with the technology it possessed, it had to be completely non-human and it had to be aggressive.
After seeing through the completion of the three races, I assumed my planned throne of the UEL.
I perfected the race I was to rule as their everlasting emperor, and started the flow of time within my mindscape.
During my first millenia as ruler, I dedicated myself to extend my race's dominance to span the current galaxy, it gave me a sense of accomplishment, it was rather simple as there was no resistance from any alien empire.
I had by now relinquished control of the other two races, and they were using my minds computing power to achieve progress along the path I subconsciously designated, making them completely autonomous.
I had just commenced invasion of Earth, without the use of orbital weapons, when I lost control of my dreams.
It was supposed to be a simple invasion, infantry on infantry, air on air and air on naval.
