I think i might have encountered a ghost!

Okay, so here I was, minding my own buisiness on the computer in the nice, warm house with no windows or doors open. I feel a burning on my cheek, an icy sensation right below my elbow, and goosebumps for no reason. I'm on the Criss Angel website chat, and I tell my friends this. One of them says to say out loud "Whoever you are, not to bring good, you must move on." I think this is bull crap and continue chatting. I get really scared from these sensations after a while, and I say the line. The sensations stop, and a tense feeling that hung in the air went away. The tense feeling has returned, but I think I'll be okay. Tell me what you think about this!
