Actually, that is exactly how psychics work. An ex-satanist and "psychic", John Ramirez, tells how he used to get money from clients. They enter, he listens to a demon tell him some things about the client first. Then, he gives a future "reading". The reading is usually a series of curses.
Here is an example (let it not fall on anyone):
"Your husband is going to have an affair and your children are going to become addicted to drugs. I can break this for you.... (for a fee)"
They will say things like, "You have a great, unrealized power.", "You are actually someone special, a heavy hitter." They will work your ego against you. Slowly, slowly, they will get you to buy them clothes, books, candles and other things to burn- but, they return these for refunds.
Look at the story of King Saul- he "perceived" he saw Samuel in the fire. But, it was a demon. The demon then cursed Saul, and all the curses came to pass.
To break any "readings" (curses, really) that you have ever received- repent to God first, then proclaim them broken. Command any demons working against you in any area of your life to be gone.
