I dreamed that my sister was too ill to return to heaven, but she recovered two days later! What's going on here? Looking for dreams.

I read Freud's Interpretation of Dreams and tried to help you understand it. In fact, dreams cannot predict the future. They are just your subconscious, which means you should not worry too much about your sister's health. It is more likely that you are worried about your sister's health recently, or that you are worried about other people's health. By the way, are you on good terms with your sister? Are you subconsciously dissatisfied with her or jealous? According to Freud's book, many people actually dream that their brothers and sisters are seriously ill, because their parents may have preferences when they were young, so the dreamer is a little jealous and wants to make his brothers and sisters sick. This is human nature and beyond reproach. As for her recovery, it may be the correction of your selfishness and the return of your love for your sister.
