Since November of last year my Aunt has been having trouble remembering her dreams. She used to remember them or certain things that might have happened in the dream but it seems that all she has now are dreamless nights when she sleeps. There have been a few occasions where she remembers certain dreams but it's not quite as often.

Does anyone have any tips or advice I can give her? She really doesn't understand why this is happening to her and she really wants to remember her dreams like before.
