How hard would it be for Rowling to get into the head of a 12-20ish year old male wizard? Why, I'd say it's nigh impossible...girls can't do that!
I met a man when I was kidnapped by police and taken to a psych ward for not poisoning my brain, he saw dead people. He literally saw a dead guy in a very old wheel chair in our room. He experiences are not fake, they are real.
He saw a little girl at the park. He looked in her eyes, he told me when you give them your energy they often will approach you. She told him she was lost and didn't know how to get home. The girl told him her address and he offered to take her home.
When the girl got in the car, the door physically opened and closed.
He approached the girl's house and knocked on the door. He said he meant no disrespect, and asked, did you lose a daughter at a young age? He explained she was standing next to him and he had brought her home from the park.
The mother broke down into tears. She offered him a $1000 check which he refused.
The two worlds intertwine.
It's very possible.
Regardless if they channel for real, they have some good info.
If you're telling us that some guy told you that, then it must be true!
