I get them at times of stress... a very unpleasant sense of having been here before, and accompanying it a sort of fuzzy depressed feeling in my head, like there's a weight there. I wonder if actually the deja vu causes this feeling, or the other way round.
I usually say that I think it's the brain screwing up, because that helps to demystify it.
However, what it feels like to me is that the previous time, I experienced those feelings in a dream. Sequences of events that didn't make any sense at the time I dreamt them do in the specific real-life situation. My dad's a philosopher, so I doubt the dream is predicting that situation, but when my brain's stressed it maybe gets into a weird mode between dreaming and wakefulness, where it interprets a strange and difficult situation in the way it does in dreams.
Actually, although it's unpleasant, I think it may have a useful purpose for me anyway. In a funny way it wipes my mental slate clean, and brings me back to reality.
I wonder what your friend would make of my deja vus. The feeling lasts for quite a while.
Love to hear people's experiences, suggestions!

I don't know what the average deja vus (vues?) per person per year is, but I swear I have at least two a month. The ones I hate are when I know what someone's going to say and/or do, and when it happens, I get that weird wave of deja vu that feels like a cross between a stomach churn and a dizzy spell.

She put it better, but basically she said she believes that something happens, your brain momentarily stalls in its processing of the information, and by the time your brain takes in what happened, it really already happened. You just don't know it, so it feels like deja vu. I dunno.
