She woke up from a nap and forgot who my sister and I were and told us she didn't have any children. About fifteen minutes after we woke her up she started to remember who we all were. She was in a time set of when she was sixteen and thought her mom was coming back to get her. She didn't think she was in her own home. She has been acting like this for about two weeks. Are there things that I can do to help comfort her or help?
