Does anybody else feel like their head is jerking gently back and fourth or like it's a bobble head basically ? I don't even really think it's moving half the time, if it is it's a very subtle movement it's not like my head really looks like it's jerking.. but for the last three days or so I've been having this. Feel like my head isn't still and is gonna fall back and it's kinda freaking me out.. I know anxiety can cause a sensation of the floor moving , but this is more like my head and I are the ones moving!?
