Hello, I'm an expert in dream interpretation. Now let me answer your question.
Scientific dream interpretation:
Dreams are the function of the subconscious. What you see, hear and even think during the day or at any time will become fragments. When you are asleep, some parts of your brain will start to combine the previous fragments to form a story.
Nightmares are actually things you are afraid of, such as fire, snakes and ghosts. For example, if you are worried about your nephew, you will be afraid subconsciously, so dreaming about ghosts or your nephew at night will become nightmares. It's okay to let nature take its course. This dream actually doesn't mean anything.
Formal dream interpretation:
Dreaming of a dead person means that some bad habits may break into your life. If you can't stick to your willpower, you will lose it to some extent.
Dreaming of the death of a friend or relative means that something sad may happen to you, or that you or your relatives and friends are about to get sick.
Dreaming of the ghost of a dead friend shows that the friends and partners around you make you very annoying and often sulk in your life.
Dreaming of ghosts talking means that you are almost controlled by the enemy. If a girl dreams about this, it means that you are probably cheated.
Dreaming that a dead relative will take the dead person away proves that the dead person will have disaster. Your nephew should pay attention to safety when he goes out recently. Some things are better to believe than not to believe.
Solution: Go to a nearby temple to pray and burn incense for your ancestors. For peace of mind.
