Sounds like a symptom of anxiety, but maybe it will pass? Kinda like growing pains for the brain?

39 year-old rant follows: I went through a phase where I wouldn't/couldn't walk under ceiling fans, as I was irrationally concerned that they'd fall on my head. Cracker Barrel (where they hang antiques from the ceiling) was hell. That particular fear passed, but was very real while it lasted. Much later in life I discovered I had been mostly successfully normalizing anxiety, and finally turned to medication - which works much much better than smoking and drinking, btw. Please don't self-medicate in an effort to change how you're feeling. Lots of young people turn to cigarettes, alcohol and weed in an effort to calm down. I would have had a different 20s had I recognized that I was ill. Having 'normal' anxiety levels is ridiculously great: my brain has lost the incessant 'oh crap' dialogue I had become used to. I'm no medical professional, just someone who put up with far more anxiety than was normal because I thought it was normal for far too long. Hope this info helps, good luck and good on you for recognizing that something is a bit squirrelly.
