Okay I'll give out a full-on response since I have the time to.
Oracle/Medium/Psychics are real, but sometimes they are lying to you just so they can get paid telling you what you want to hear. Everyone wants to hear that they're special in some sort of way, but we are all equal. Every last one of us. No one has powers, no one is above anyone else. We are equal.
Seeing things before they happen is normal. Everyone has psychic abilities, but some just choose to ignore them. The future always changes, and is never set in stone.
"Sometimes I make stuff appear"
This one baffles me. Because you cannot create energy, or anything, out of thin air. Energy is only transferred. Point of that is saying that you can't make things appear.
I am helping you by telling you the truth, dear.
