ufo video

I was just reading an article about a large ufo sighting in Brazil last month http://forgetomori.com/2008/ufos/ufo-photos/the-caratinga-vortex-ufo/ . The site a pics and a video of a "vortex" ufo. I've never really seen anything like this. The video, if authentic, is excellent and would be hard to explain with the usual bullshit the scientific community and military give us. I have had several experiences since the early eighties that give me a very deep respect for the "unknown".
Back in I think either 1982 or 1983, one of my best friends lived in an old apartment building right across the street from Levi Strauss Co. on Valencia st. here in San Francisco. I lived around the corner on 15th and Guerrero st. Where he lived is now a Greek Church and a private high school. When the Greek church bought the property they decided to tear it down and rebuild on the site. Everyone moved out except my friend and his mom, along with 2 other residents in different units. The building was 4 stories high and had 30 some odd apartments. My friend and his mom lived on the 3rd floor. An elderly lady that was one of the two other people that still lived there also lived on the 3rd floor until she passed away there. The realty company came and removed the locks off all the vacant apartments and my friend decided to use one of the apartments for a hang-out and a spot to grow weed. He had a nice marijuana plant growing in the corner of one of the rooms in an apartment above him on the 4th floor. We had the old blackout shades from our junior high school in the windows so people couldn't see in. It would be hard to see in anyway because the apartment was higher than the closest buildings on Woodward st., which was half a block away going east towards Mission st. One evening around 9pm we were kicking back in the apartment talking. We had the black shades down so we wouldn't be seen in what was supposed to be an empty apartment. The people in the apartment were my friend that lived in the building M. Rojo, another friend of ours, R. Rivera, and myself. Suddenly a solid circle of light about 10" in diameter appeared on the shades. The light appeared to originate from the inside, where we were, not outside. All three of us noticed it and quickly focused our attention on it. Suddenly it's diameter shrank down to about the circumference of a quarter and started to come across the room. Not like from a flashlight or any other type beam of light because they would go straight across the room to the other wall. This light stayed the circumference of a quarter and slowly came across the room like a stick being pushed across the room. Rojo stopped talking and sat trancelike. Rivera began to cry uncontrollably and became hysterical. I got up out of the chair I was sitting in and moved across the room towards the door. As I crossed the room I could actually see the front end of the beam of light that now looked like a gold/bluish laser except that it didn't go all the way across the room. It was just like a stick being pushed from the window towards the opposite wall but it was a beam of light. It moved very slowly and when it finally got to the opposite wall it made a circle (with the beam still in tact). The circle was the size of a quarter and then it widened suddenly to the size of a small plate and then back to the quarter size. Slowly it began to change the angle of the beam and the light went up the wall. When it got to the crease where the wall hits the ceiling, the light "exploded". It blew up similar to a camera flash, a light bulb blowing out and a television blowing out. When it blew up it literally soaked the entire apartment with the brightest light I've ever seen. It even lit up the other rooms around the corners from the room we were in, as well as under things in other rooms (the bathroom and kitchen), which although the whole episode was frightening and bizarre, was the only thing that finally shocked me at the time. It lit everything up so bright and so long I was able to go out into the hallway and see that the other rooms were lit. Suddenly, the light which actually had become like a coating of the entire place began to quickly retreat, like video played in reverse or if you used a very powerful vacuum on a cloud of smoke. It all went right back to where the wall hits the ceiling, changed in size again from the small to the large and back to the small and began to slowly creep back across the room towards the window, exactly like a stick being removed. During all this craziness Rivera was still beside himself and Rojo was still in a trancelike state. Finally it made it back to it's point of origin, the blackout shade, circumference from small to large to small again, then disappeared. I made it across the room in 2 quick steps and lifted the shade: absolutely nothing. Rivera almost immediately stopped crying and Rojo started talking again, on the same subject he was talking about before the light appeared. Never found out what it was. A guy in Sacramento actually was dead on in description of a similar experience and then suddenly started making about as much sense as most of the people you see on the street with far away eyes talking to themselves. As I stated before I've had more than one "strange" experience. The first two I happened to be in the company of the same Mr. Rojo. Synchronicity?
I gave this same info to one of the top scientists/ ufo "expert"s in the world. I won't say his whole name but he's from Germany and his first name is Karl. He told me it was ball lightning. Fuck you. Get some new generic phrase for shit you can't explain with "science".
