Every so often (about 3 times in the last year), I'll have a strange experience, I'll be in the bathroom or my bedroom getting ready for work in the morning -- and I'll suddenly feel like I am remembering something that happened in the past. It's sort of a deja vu feeling. In my mind, I see a picture that represents the event, but it is like I am only able to see that there is a picture, but not what is in the picture. Then my heart starts pounding, and I feel dizzy. I feel very afraid, but don't know why! And it almost feels like the world is tilting, and I feel a bit like I am going crazy. There's a lot of anxiety with it, which makes me feel like I need to go to the bathroom. I usually sit down on the bed and just try to deep breathe and get myself through it until I feel like myself again. The whole thing from start to finish only lasts maybe 2-3 minutes. But it's so unsettling!

Has anybody has something like this happen to them? Does anybody know what this is?
