This Can't Be For Real

"Chance!", yelled my brother. He came running up to me breathing deeply and started talking in a scratchy voice.
"Chance come back to the house, there is no reason for you being out here in the woods by yourself."
I noticed that he wasn't being his usual self, most of time he is all fun and games but now he seemed curious.
"Mom said to come back to the house she", he paused "What are you doing anyway"?, he asked with a concerned look.
"Oh I saw this on the internet and thought it was all a big fake so I just tried to see what it does",
My brother is John and he was a blonde, he was wearing a white t-shirt and black pants with slides on. He's 15 and I'm 14 with a black shirt and tan cargo shorts with high tops, us brothers have our own completely different styles.
He saw my things I had sitting on a rock next to me which were Salt, chalk, a pot, and a ceiled small bag of chicken blood.
"What are you doing down here?, some kind of ritual?"
