Hello Challoran: I'm sorry I cannot offer any useful insights into what happened to you. Personally this does not sound like a psychological or psychiatric event to me. But I'm not a mental health professional. I also don't know what else it could have been. I guess the good thing is that, once it was over, it was over... hopefully never to return!
I see this is your first post here on NeuroTalk. So I'd like to welcome you to NT.

I hope you find whatever amount of time you spend here to be of benefit.
