Your dream is a mess, some real people, some bloody scenes.
Because I don't know your real life, I can only say it in general.
Dreaming of dead relatives is a common situation in dreams. Generally speaking, it's not that you miss them especially, but people you never thought of at all on weekdays. Dreaming that they are just a medium. Mainly what happened in your dreams. Reflects your recent inner impetuousness and insecurity.
Your desire for affection and subconscious desire for the attention of relatives and friends make you feel insecure, afraid to leave your relatives, or afraid to leave your relatives.
Recent changes in solar terms are easy to be impetuous and easy to dream at night. It is recommended to eat some cool and detoxifying food, sleep not too hot and relax your nerves. I hope I can help you.
