I've also heard the intense summertime insect sounds that suddenly shut down or morph into "electrical" sounds.
I've heard these sounds....
I hear an "electrical" sound now that I have, for months, attributed to my ears ringing but it DOES seem to come from the center of my head and not from my ears. Don't know the cause of it. Been happening since January and I am nearly used to it now.
I have also seen someone "morph", it was terrifying! I do not entertain a "spirit of fear" as I know where that spirit originates but I will tell you that when I saw this girl change, the fear I felt was indescribeable!
I have no idea.... I heard them just a few weeks ago as I was out walking my dogs. I stood and listened to it for a few minutes... and progressively it went from insect-like to electrical...
That is SO STRANGE that you put it that way. Just two days ago, my husband and I heard what sounded like a million crickets in the field by our house. It was way too uniform, though and we both agreed it COULDN'T be crickets that we were hearing. Upon further investigation, we realized that the POWER LINES were making the sound...sounded just like crickets!
Must be!
Case of the crickets ---- SOLVED :)
