Trumpet sound in sky after thunder storm in Southern Ohio

Hi...

I am new to this site! So please, hang in there with me! This past June after a thunder storm passed, I was on my back deck and all of a sudden I heard this weird sound coming from the sky. At first it sounded like metal scrapping metal and it got louder and then it sounded like trumpets. It did it 2 times and that is when I yelled for my husband to come outside. We both stood there amazed at what we were hearing. I honestly was scared! I still hear that sound in my head. So, I did an internet search... and was blown away at other people have heard it. My husband said it was "ions in the atmosphere" making the sound. I think it was a SIGN! Now my husband thinks I am crazy!

My question is... Am I crazy because I think it's a sign?
