So I have always gotten a random shiver/chill/cringe once in a while. It only lasts 1-2 seconds but my head kind of turns back and fourth. It's fully automated, I have no control over it. Maybe once a day? I was sitting next to my friend jamming and it happened, and he was like "wtf, are you okay"? I asked him if he gets random shivers/chills once in a while and he said no. So I was wondering am I the only one? Do I look like a crazy person? Sometimes it happens at awful times - when I'm taking a piss is the worst because I'm trying t multitask my aim and still let the shiver come and pass.
