i used to believe that small spirit people (i didn't consider them fairies but it's the closest catagory) were following me around and were only visible in my peripheral vision. as soon as i'd focus on them they'd disappear. they were not evil but rather more curious and watchful of my activities. i wasn't afraid of them and would consider noticing them a good sign that i was doing something interesting to others. i stopped noticing them at about 10 or 11yrs old.
