High pitched sounds & bright light in my entire yard at 3:30 a.m.I was awakened by a loud noise that sounded like a base drum going Baboom,Baboom, several times. This proceded into a high pitched sound that would change octaves for a long period of time. I thought I was losing my mind so I got out of bed and went to look around the house to see if I could find what it was and my 3 acre yard was lit up like daytime. The high pitched noise would start up, then stop for 30 seconds or so and start up again. My husband also heard these sounds when he woke up so I know I wasn't dreaming. My cat was going crazy running around the house like a lunatic. My brother lives three miles away from me and we also work at the same business and when I was telling him about it the next morning I couldn't believe it but he had also heard it. I could not see any form of craft in the sky but there was a very bright light shining down. This was wild! Finally everything stopped on a dime and it was completely over with.
