No, not hissing. But last couple of years there is like a high frequency tv is on sound wherever i go. at first i wondered if i was getting tinnitus, but my 12 y.o kid also hear it and sometimes complains it being so noisy that it prevents him from sleeping. i have no idea what creates this but it started escalating after my parents went and got the shots and then got covid , we did not take the shots but then we also caught "it" a week after them getting it wich was about a months after their 2nd shots.. (have no idea if its related or if it was coincidencally that i started notice at that time tbh)there has been several symptoms after that , rashes that itches all over the body. Pains in muscle/bones and this incessant loud High frequency "tv sound" in head or ears. nowadays i can hear it myself all the time allthough it becomes stronger or weaker at times. At times ive wondered if im going nutz..
Dude that I work with has an uncle living with him who took the jabs. He suffered a failure of one of his organs. Liver or pancreas, I forget which. Now my friend is saying he thinks his uncle is shedding the spike protein which is making him feel stress and an elevated heart rate. He tells me this after telling me some of the irritating things his uncle does. Uncle is basically a little kid now and has short term memory loss. Dude smokes weed throughout the day in the house. Yeah, I dunno.
I'm not saying that the shedding thing isn't a concern. I just haven't heard nor seen enough that I am convinced yet, but I am as always, suspicious because Bill Gates would love it if they could make that happen. Then there is the matter of just how many radio waves we have flying around in the air around the world.
It is exactly this sort of attack on humanity that helps me understand that when Jehovah finally takes off his belt, there won't be any questions afterward.
As a side not, I've been hearing hissing and ringing since I was a kid. I notice it at certain times and then it goes away. Don't panic, yet.
