Pulsing Blue Ball of Electricity Making A Loud Siren Noise Vibrating my BodyMe and a few mates were at a party and we were just going for a stroll down the road, when suddenly we heard this very odd sound. It was a very frightening sound, it felt as if it was vibrating my body. This is going to sound ridiculous but it sounded exactly like the siren from the movie The War of The Worlds. Anyway, as soon as we heard the sound we turned towards it's direction, and a huge, blue pulsing ball of lightning appeared, and started contracting expanding and getting louder and louder and brighter and brighter. After about 15 seconds it shot of to the left, not sure of the specific direction, but this was the most amazing thing I've ever witnessed in my life. All my friends sprinted back to our houses in fear thinking UFO's have just made official contact with earth. Anyway, I haven't seen any reports about something like this. I'm so curious as to what it is and I cannot think of any rational explanation. It could not have been anything human. This light lit up the hole horizon and the sky, it went from pitch black to a deep blue contrast everywhere you looked. This has been my only UFO sighting.Think how you please but this the absolute truth. Just thought I would share.((NUFORC Note: Witness indicates that the date of the sighting is approximate. PD))
