Is it normal to feel scatterbrained and absentminded when in social situations?
When I was in places such as Times Square or at a family party my mind was all over the place. This is especially true when I am in busy and loud places. It doesn't happen all the time. For instance, I was at a wedding the other day and it was pretty damn loud and busy, but I was comfortable because I had someone to talk to.
This may induce a headache, but it is more a symptom of disorganization rather than pain.
