I guess I was about 17 years of age. I was staying at a friend's house and while I was there, we were really into the topic of auras and astral projection. Well, throughout the night, we'd seen some crazy things; red transparent hand coming out of the wall, odd shadow in the corner, and strange flashes of light.
After we'd had enough of the evening, we'd laid down to go to sleep. I was on the floor and he was on his bed. I had just fallen asleep and woke up suddenly to see a glowing green symbol on the right side of my left hand. My friend yelled my name and I looked away from my hand to look up at him, but there was a purple-ish orb above the middle of my stomach. I quickly yelled back at him and looked in his direction. Then everything was gone.
I hope that someone could shed some light on to what has happened to me. It would save me the trouble of going insane, thinking that it never happened. And if any of this has happened to you, I hope that you find the answers that you need.
