I was an adult and I was in the Edinburgh Fringe Festival. I was performing in this cave - they used to bury the plague victims in these caves underneath the streets of Edinburgh, when I got this weird cold sensation up my spine, it gave me this really weird feeling, and then I looked up and there was this white, sudden white shape, that just zapped from me and went straight to the light that was at the back of the room, and I just stopped cold and said to the audience, "Did you guys see that?" No one saw it.
