Hi my brother is having the same symptoms as a previous article listed :-

Please advise ...
Thank you

I am occasionally afflicted by a strange condition that seems to be linked to my memory and my stomach. Every now and then, I get a flood of memories, usually from dreams I've had recently. the images and events I am remembering seem to make no sense, but are accompanied by a strong sense that remembering them is important, and that doing so makes sense, like a missing piece of a puzzle that has been replaced. Very shortly after this, I am overcome with nausea, developing a sort of tingling burning sensation in my stomach and breaking out in a sweat. This lasts no more than a minute at the most, but once the nausea has past, both the memories and the feeling of 'making sense' pass. This doesn't happen to me often, maybe once every six months or so, and usually happens three or four times a day, but it's very odd. Anyone have any ideas?
