I have experiences with de-ja vu and with anxiety attacks, but not at the same time.

My exh moved into a home, a couple months ago, that is a serious de-ja vu home for me. It's been really interesting, everything that has been changing in my life. And that 'dream' I had, involving this home, back in the summer of 2007, really interesting how things are playing out.

But, as far as anxiety attacks go. There's breathing techniques, etc that can be done. Sure you can find some online or work through with your therapist. And there are meds to help, if they are something beyond your control.
