eloquently:
Have you not noticed that some of the things that happened to you or your closed ones, you saw it in the dream before it happened physically. I read of someone who said that after he slept with a lady, he had a dream of failing an exam, and he actually failed the exam physically.. I know of a woman who saw dream of death before her daughter died. Dreams are sometimes signals to what will soon happen physically. Some dreams could be warning signs to avoid a person or be careful with a person. Please never joke with crucial dreams... Some people have dated or loved people who were sweet in the physical, and probably had warning dreams about such people and ignored it. Later they saw the evil reality in the physical... Please never joke with your dreams.

What to do as a Christian when you have evil or bad dreams.

(1) If you see re-occuring evil dreams or bad dreams about a person against you, it could be a warning sign to avoid or be very careful with such person in the physical.

(2) If you see a dream of something evil about to happen to you or your loved ones, immediately you wake up, pray this prayer for about 20 minutes "By the Power in the Blood of Jesus Christ, I destroy the seed of this dream in Jesus name. Amen". Once you are done, the dream can never happen in the physical.
