How many of your experience internal shaking from anxiety?

For me this symptom comes and stick around for weeks, only to disappear for months. I haven't had it for a while, but experienced it tonight.

It only happens upon awakening at night, especially if someone wakes me. At first i thought it was a rapid pulse, but its literally like a phone vibrating inside me. I can feel it i my calves, chest, wrists and sometimes head. Its so strange.

Thankfully it doesn't last long, but can make me feel panicky. I sometimes see patterns upon waking too and again its intermittent. I have so many anxiety symtoms.
