Why did I experience a few seconds of total memory loss?

So yesterday afternoon I was driving home after presenting fitness classes to little one's. While driving a road I know very well, I suddenly did not know where I was. It was only about 10 seconds, but felt a lot longer. I got really scared. First time this happened to me. Anyone else had this happened to?

Help..... I was in my friends house there was about 8 of use every thing was ok until something happened to me it's like I lost control in my head. I was looking at two of my friends an I was stearing at them I could not recignize them I did no why I was der I just wanted to get up and run as far as possible. What's going on nothing like dis ever happened to me

Since December I have awaken on a few occasions and temporarily forgetting who is with me and who I am. It is a very nervous feeling for me. I am usually in a panic trying to quickly remember. Sadly, it freaks me out so badly until I am afraid to go back to sleep fearing it will come back again. I am so scared that this is the beginning of me losing my mind all together. I totally fear the worse. It doesn't happen every night but has happened enough since December. I have previously been diagnosed with having hyperthyroidism, which also started in December. But previously​ I had been diagnosed with having panic attacks but ultimately I found out that the panic attacks were brought on my the Hyperthyroidism. I have been on zanax and temazapam for the aniexty. Now I am off those meds and on methimazole and atenolol to help with the thyroid problem. I have been reading the threads to hopefully find out what is happening to me. If you have found out anything I would love to know what helped you. I have talked to my doctor and I have also gone to talk to a pyschiatrist and she didn't give me an explanation for this problem. When I first began having the problem it was affecting me when I was driving. It seemed as though I could not remember where I was or where I was going or even who I was. I would repeat my name over and over again also repeating different family members names. Just to convince myself I wasn't forgetting things that I should know.If you or anyone could help me figure this out I would be so grateful. Thanks to all.

I did that in work the other day and panicked ..it was horrible and tears come to my eyes when I think of it .i work in a care home with alziemer residents

It happens to me a lot!!! I mean there are days that I'm really normal but than once in a month maybe in a day I feel lost and I recall some strange things from my childhood, I don't know who I am or where or what am I doing, I just kinda black out and I have to calm down and to stand up and walk for a bit to go to normal. It can happen 5 times a day, something is wrong with me but idk!!!
