Then I bet my aura is purple. :p
I've had those types of things...
when I was like 8, the lights were off in the hallway and the living room and the TV was still on...
I was walking down the hallway and saw a light bouncing off the edge of the wall, and it was like a string and it looked like it was twirling n' such and I thought that was a ghost/spuernatural being...
after much running in fear, it was the light from the television that caused it, and after a quick experiment, twas true... Stuff can be explained.
