The other day my sister asked me to play Yahtzee with her (a game we have previously played on numerous occasions). I apparently said I could not remember how to play. She kept asking me but I did not remember. She eventually thought I was purposely annoying her and shw went and got Dad. Upon Dad questioning me he became worried and took me to the hospital as I could not remember basic things. I apparently would repeat the same question over again yet it was as if I didn't hear the anwser so I repeated it more. The doctors ran a few test yet could not diagnose me. Upon me waking up the next day I had no recollection of this but I felt like I had a hazy dream about a hospital but nothing else. Before this occured I was perfectly fine, its almoat as if a switcj flipped and I lost my mempry. Can anyone tell me what they think happened to me or if this has happened to them? Also should I be concerned that this may happen again? Any help would be greatly appreciated, thanks in advance.
