For the past couple of months, I have been randomly woken up with what feels like an earthquake or my cat scratching itself on the bed. However, when I sit up to look, the cat is sound asleep and then the vibrations stop. I feel it in my whole body, but sometimes just my legs. It doesn't happen every night, but it is the SCARIEST feeling... Am I have mini seizures during my sleep?? Is it anxiety? Neuro issue??

I am actually seeing a Neuro this week for an EMG, so I am going to mention it. But has anyone else experienced this? It's freaking me out.
