I went outside into my backyard to smoke a cigarette around 12 Midnight. I habitually look to the sky to see stars. It was overcast. For some reason I noticed a blue-white figure of some sort that appeared above the house diagonal to mine from the backyard over the roof. I got scared at first I thought it might be an invisible entity monitoring me. I noticed it was kind of invisible and you could not see it by looking at it directly. I could only see it through my peripheral vision so I had to look at an angle. I got closer and farther away and figured it was not an entity or it would have moved more as opposed to being stationary. I noticed it was a lot of small blue-white stars or spaceships shining through the clouds bunched up. They formed a tree like triangle pattern. Occasionally some of the objects would move into different patterns. One looked like the peace symbol you do with your fingers. I saw them make a straight vertical line and I also saw other shapes I could not understand or make out. It was really hard to view them since it was out of my peripheral vision only, looking at them straight on would make them turn invisible or nearly invisible. They were very far away south west. Probably from space shining through clouds. They eventually mostly disappeared.
