Is it normal that people hold their hands on their nose around me?

Of course you brush your teeth everyday. That was a stupid question on my part. It probably is paranoia. Sometimes the mind plays tricks on us. I remember a few years back I thought I was pregnant for a few months having all the symptoms, nausea, headaches, weight gain, no periods, etc. But I went to the doctor it turns out my I wanted to have a baby so much, even though I wasn't thinking about having a child at all, my mind and body created this "ghost baby". This isn't relatively similar to your story but all I'm saying I was embarrassed and ughhhh. And go to doctor
