A fortune teller told me that relatives would be shot.

I consulted my psychology teacher about this dream. It's called subconscious reflex, that is, the scene you were thinking about some time ago suddenly stopped, and it's easy for that scene to appear in your later dreams. This has nothing to do with your mother, because your mother's shooting is a probability event to buy lottery tickets, and all the previous factors have been received by you, which is reflected as a two-color event by dream calculation. If you don't win the first prize in the lottery twice in a row, you don't have to worry about it anymore.
