I was diagnosed with RRMS in 2001. Every so often, something odd happens, & it only happens when I'm sleeping, or at least trying to. The only way I can describe it, is it feels like my brain & eyes are being squeezed and released, sometimes to the point that I feel like I'm gonna black out. It's not painful, but it's very uncomfortable and quite scary. It wakes me up out of sleep. During the part when it feels like everything is being squeezed, it almost feels like I'm frozen, like I can't move, as if I'm being electrocuted. I can also hear some kind of noise in my ears, almost like a buzz sound. This is not the same as when you tilt you head and neck forward & feel your spine vibrate. I have had that during relapses. This is totally different. Has anyone ever experienced this??
