it's been happening to me on pretty much every day basis. usually when i'm outside, e.g. walking my dog or if im going somewhere with my boyfriend. occasionally at home too. at first it's impossible to tell them apart from 'real' people. but when i try to actually look at them, they disappear. sometimes i see spiders or glimpses our dead cat when at home.
my friend thinks i might be seeing ghosts/spirits or something like that but idk. can anyone relate? i'm wondering it's something with my vision, maybe. do most people experience that sort of thing and is it just my vision playing tricks on me?
