I suspect most people here are NOT having AFib but have vibrations during sleep or just entering or coming out of sleep. I am one of them and I can guarantee, it's NOT Afib. What you wrote above is quite accurate but not what's going on for most of these posters. It seems to be one of three things, covid related/long hauler symptom, sleep disorder, or anxiety related. No I am not a health care worker but I know enough to assume it's probably one of these reasons. Not to say some may not have AFib but that condition does not cause these forms of vibrations for extended periods of time, unless someone enlightens me otherwise! I brought this issue up with two physicians and neither thought I should be checked for AFib or even mentioned it but everyone should discuss with their own physician.
