I came home after work and my wife was curled up on the bed crying hysterically and talking in the past. She was crying about our dog Sally dying, but Sally died at least ten years ago and talking about our children being 6 and 7 years old but they are 34 and 36 years old. Not remembering our new dog Jack and thinking she should let Jesse back inside who was another dog we had 15 years ago. She also seemed to not know who I was and starred at me all the time. After about 15-20 minutes it was like a switch came on and she was laughing and talking normally and not really remembering much of what she said or how she was acting. She is on anxiety meds and has been out for a couple of days and I had her new pills that day so after some convincing her to take them she did and that is what I feel made snap out of her condition. What was going on?
