A widely known omen?

Maybe I didn't express myself properly. We believe that if a deceased relative comes to you in a dream, it means that you will receive news about the death of a close or familiar person. This sign is especially strong if a relative who died a long time ago came to you in a dream. It is quite possible that this is all delusional. But such a coincidence also happened in my family, so I believe in it.

Maybe they were so incredibly angry at the Germans

Perhaps so. But I listened to the program of the Russian journalist Nevzorov, who quoted the memoirs of the Russian military. He convinced that the Russian army behaved this way in the First World War and in the Second World War. I can neither confirm nor deny this as I was not a witness. Journalist Nevzorov is now forced to live in Italy, and has also received Ukrainian citizenship. He may have subjective views.

I think that many things happen during the war that you don't want to remember later, on both sides. But somewhere there are only a few such stories, and somewhere it is a mass phenomenon. I only know for sure that your people have lived through terrible times and I would not wish that on anyone. For Ukrainians, the Second World War was also a disaster, and this disaster did not end in 1945, but continued for a long time. But this is a completely different story.

P.S. Your posts always spark a discussion, not my fault.
