yes I also feel like this, I also get a sudden loud buzzing noise going in my ear and through my head which always started a panic attack off, now im used to it and it only happens when im stressed, I still freeze for a few seconds but remain calm [ish] and it goes.
I also have horrrid feelings as im falling to sleep, and I wake up in a flash, ive had a really really loud noise [which hasnt happened for a while now thankfully] it was like someone whistling down a bottle only a 100 times louder, it made me feel like my brain was vibrating and then I would get a dream of me being awake and getting up, it was horrible, ive had it loads of times but not lately. I bet I get it again now
