A Brief Explanation of Some Symptoms of My Mental Illness

My dream this morning. (2015-08-04: Approximately Noon Pacific Daylight Time)

I had an interesting dream today (Tuesday) around noon. I was sleeping in bed since 5pm on Monday, the previous day. I went to bed around 1:30 am Monday morning, but unfortunately, I failed to fall asleep. I remained in bed trying to fall asleep until 5 pm that day, when I finally fell alseep and slept until around 12:15 p.m. today, which is why I guess the dream happened around noon.

This morning I had totally awesome higher power superpower dreams.

It started off at Mizar Place where I was in a really weird altered state and my brother and Dad didn't trust me with anything dangerous. While in my altered state, I tried to explain to them that I knew what danger was. I used the stove as an example. I explained that the burner was hot and the pilot light had to stay lit or otherwise gas would escape and catch fire.

Then there was a super loud arcing noise coming from what sounded like miles away. Just super loud electrical sparking type noise. So Dad and I went to investigate. We drove several blocks until we found a military zone full of security guards, then we found the source of the noise. There was a huge gigantic antenna that had been built, and there was a house where there were sparks and the sparks were being amplified and broadcast out some kind of elaborate speaker unit.

There was a military cop that greeted us. Dad had a .45 pistol and I had a small .22 pistol. The cop asked us if we had permits for the guns. Dad said he did but that I didn't. They took my gun.

Then we tried to figure out what the gigantic antenna was for. Dad guessed that it was classified but he said he thought it had something to do with extending the range of antennas at Vandenberg.

Then we drove to Vandenberg. It was clear that there was something big going on. There were all kinds of advanced aircraft flying around really low to the ground.

Dad and I and my brother and one of his friends were in a van. We saw a helicopter-like aircraft fly really low by us and we could see the pilot through the windows. It was a really beautiful woman.

Then all of sudden, the beautiful woman was in the van with us. She explained that she was able to sneak up on us without a sound and enter the van without evening opening the door. She explained that they had advanced nanotechnology and the ability to move and reassemble atoms.

Then she took us to a place where there were spaceships from aliens and they said that we were selected as part of a small group of people would now go with the aliens. She took us inside one of the the alien spaceships.

The inside of the spaceship took us to another world that was filled with ancient hieroglyphics and giant aliens.

They explained that they had been looking for a human god to control the spaceship, and I naturally didn't want the job because I had so many flaws and limitations. Then they took me to the alien god who was in charge of the spaceship.

I was trying to explain to Dad that they had advanced nanotechnology and that they could do anything to us and then return us to perfect health. I tried to explain that there was nothing to fear.

Then we were in a giant building that went on forever and it was filled with sleeping mummies that were starting to come back to life in perfect health. I remember saying that I would like to be the walls and floor of that building.

Suddenly all the walls to the whole building turned into gold, and all the floors turned into golden-colored marble. It was all beautiful.

Then the aliens started demonstrating that they could kill us and revive us to perfect health, even better than we were before.

Then things started attacking us. There was some kind of dog like creature running towards me. I just stood there waiting to see what would happen, knowing that I would be fine. Then a group of four aliens were coming towards me. Again, I stood my ground and didn't run.

They attacked me then quickly called off their attack, and I was repaired to full health.

A bunch of stuff happened that is escaping my memory, but the last words of the dream were from the inside of a golden palace and the leader of the aliens said to me, "You're immortal soul is with us, the angels."

Then I woke up.
