Dreaming that many dogs were run over by cars, is there any omen? !

I once read a newspaper that people's dreams are only good and bad. Dreaming is part of the brain's activity at night, so it can't be said that it indicates anything. The quality of dreams does not mean what will happen in the future, but predicts some possible things according to the current situation around you, so that you have the ability to deal with these things, only the ability, that's all.
