Have I Met You Before?

have you ever had a feeling that someone in your class or someone you saw on campus looked very familiar even though you know that its your first time seeing that person?

I felt like that today and ever since i started college
random people i see looks very familiar
like today we were doing group work in my writing class
and this girl in my group named teresa who looked and sounded so familiar
so i asked her where she was from
she answered "i am from the valleys, i lived here for all 18 years of my life."
so obviously it was my first time meeting her, or is it?

i have 2 theories about the reason behind why we feel someone look so familiar even though you just met them

1) i call it "indirect meeting memory theory"
when we stand in line we dont look at one place and focus, we look around
we look at the clock, other person in line, people passing by, and etc
so when we see these people, our brain puts the faces of people we saw in our memory
and when we happen to come across that person, we get that familiar feeling

2) look a likes, there has been many celebrity look a likes so why not look a likes of our friends and family members. a childhood friend look a like will surly give you a feeling that look a like looks familiar, but this theory has holes.
if a person who looks like our friends and family give us that familiar feeling, then shouldnt we know that this person looks like our friends and family?
a flaw in my theory

as for teresa, i think 1st theory fits in the best. teresa doesnt look like any of my friends or family so my guess is that i saw her on campus when i am in line for something, going to class, or even in the parking lot, possibilities are endless

think about that...
