Is this a silent migraine?

I've been having these episodes since I was about 16 but just usually ignored them, I told a doctor once and they didn't have an answer or be very concerned so I never brought it up again. Now that I've had my second baby and am not getting much sleep I'm getting them a couple times a day, same happened with my first. Sometimes I can go months without experiencing anything though.

My symptoms include a general feeling on malaise during the day and a bit of a fuzzy kind of consciousness. I guess I experience what you would call an aura because before it hits I know it's coming and I get a super anxious feeling then with it hits it's like my brain gets scrambled for a second, I get very dizzy and I usually stop whatever it is in doing because I can't concentrate or even find the words to talk. Usually my brain jumps to some strange memory and replays it in my brain while i sit there waiting for it to be over. It only lasts about a minute or 2 usually just leaves me dizzy and confused and a little nauseous but then that leaves after a few minutes and I'm back to normal. No pain, no flashing lights...I don't know what else it could be. Any help would be appreciated.
