Can anyone say whether Earth technology can manifest itself in this way?

Here is a schematic representation of what I observed in the night sky a few years ago, by the way, looking out the window. I turn off hallucinations. They have never been dealt with. Does anyone have any explanation for what this might be like if we exclude newcomers from another dimension or the expression of extraterrestrial reason? I haven't received any explanation yet. If cosmologists, meteorologists or other specialists do not explain anything about such maneuvers, then, albeit involuntarily, suspicions fall on aliens. The former co-worker said he had seen something similar. Cousin agreed with me that these could be modern satellite technology, but a change of direction at such a sharp angle and out of nowhere and sudden extinction? I sent this scheme with a description to the Latvian Astronomical Society. No answers yet. Ha, ha, maybe they already have a certain attitude towards such observers. Then I'm sorry because I didn't fantasize
