I thought I was literally losing my mind until I stumbled across someone else who is going through the same thing. There's a noise at night, its such a low frequency you can hardly hear it some nights, and it causes our bodies to feel like they're vibrating inside like a tuning fork. Its causing horrible panic attacks- numbness, nausea, shaking, terrors... its absolutely awful. We've been tested for MS, had MRi's and CAT scans, gone by squad thinking we're having strokes and/or heart attacks. I've followed it some 20+ miles one night when it was particularly loud, my dad was able to hear it and feel it. It actually shook the car when I stopped. The stress is causes our bodies is exhausting- anyone who has stress or anxiety disorders would understand the physical toll of a single panic attack- let alone nightly ones, or ones that literally last for days at a time. We've been sleepless for days on end with this thing. Its just horrible. We have no idea what it is. Its almost like a jet plane in the distance, or a freight train far far off- it rumbles and cycles. wooooomwooooomwoooooomwooooom. it is absolutely horrible. There's videos that we found online of similar noises- i guess there was one during an oreols game in florida, and other states too. Its been on the news in other areas, but they dont know what it is. Iam thinking maybe there's a wind farm some place that just opened or something. Its only been going on since august. Anyone else? Anyone?
