I suffer from severe anxiety, panic attacks, Hypochondria and Tourettes (among other things) and from time to time, I'll just be sitting or laying there and get this sudden feeling/sensation like my head and/or body is moving/shifting a little bit to the left, right, up or down. Shortly afterwards, I'll have a panic attack because, well, it's pretty frightening.
Has anyone else here ever experienced anything like this before and is it fairly normal for anxiety?. I also get bouts of vertigo about once or twice a year (my mother has this too) but this does'nt really feel like vertigo all that much. It's more like a "movement hallucination" or just the sensation that your head or body is falling, shifting, moving, etc. Really scary!.
