The opposite of a déjà vu
 

I don't have déjà vus.
But on rare occasions i have this mental experience:
I see a person that i know for years and s/he seems to me like a stranger. Almost as if i am meeting the person for the first time.
A slightly irritating and alienating feeling it is.
Anyone know it?

I get that with words sometimes. I'll see an ordinary word and all memory of what it means or ever having seen it just -- poof.

That sounds like a great way to approach people, though -- always meet them as if for the first time, no preconceptions, no second-guessing, a fresh new start. In fact, it IS a new person each time you meet.

You're lucky!

Ah yes, Wikipedia calls this phenomenon "jamais vu" and states examples of tests with words.
No, you are lucky! Learn a new language every day. :)
Don't see any use in it. Just an odd feeling that lasts a few moments.

One time, back in high school, they were handing back some school pictures and when they gave me mine I could not recognize it as myself for some bizarre reason. I looked at it, and literally did not recognize it as myself, and tried to give it back saying it wasn't me. Needless to say, someone probably thought I needed crazy pills.

Years ago I read a fun novel, that dealt with "jamais vu" in a trippy way.
Very cool book.

Here's the book.

Jamais Vu Papers, The (Paperback).
by Wim Coleman and Pat Perrin

You remember that thread about the man who has a memory of about 10 seconds? Every time he saw his wife, he was like he hadn't seen her for hundred years.

I don't remember that thread anymore, if someone wants, you can search. :)

Anybody else experience forward time shifts? Like hearing (answering) the phone before it rings or answering a question before it asked being sure you actually heard the phone or the question even tho witnesses say it didn't happen.

I get that a lot and it's often just mundane stuff. There have also been times when it is hugely significant as if I'm being prepared in advance.
It's precognition.
