WTF is ‘deja vulnerable’?

Its the feeling that autocorrect is going to fuck up your question 1 millisecond before you click post.

That feeling that you've already lived through this exact monument.

An autocorrect sorry

They don't know yet. Any answers you get here will be guesses.

Like the other poster said there's no cause known. All I can think of is something happened so close to an experience (something you can actually recall is a different matter) or perhaps something you've experienced peripherally such as a dream or media.

Or perhaps just something so close to one of those you feel like it's happening in front of you.

Or just a glitch in the brain?

Or perhaps it's the Matrix shrug unsure if that's better or worse.

Or....

I read somewhere once that one theory behind deja vu is that it's the result of a temporary de-sync between your left and right brain hemispheres. Usually signals reach each hemisphere at about the same time, but sometimes the signals can be de-synced by a few milliseconds and (theoretically) cause you to process the same thing twice in quick succession, giving you the vague impression of familiarity on the second signal process.

Edit: Messed up a bit. Each hemisphere sends a signal to the temporal lobe for processing, and that's where the de-sync can happen.

I did wonder if it was autocorrect, but damn that's a huge leap.

Look, if you didn't get it last time we told you, you won't get it this time.
