This is a Q from my 90 year old mother, Hilary - 
She has noticed over the last 6 years or so her dreams have become much richer and more about the people from her youth (so many of them have of course now died). They are all happy dreams and really rich in colour.
And she  says they are a completely different style of dreaming now, though hard to define why apart from colour and enjoyable time with people of her past in them, just not same as before.

The change in her life was this - She had explored and studied dreams in depth and helped others interpret theirs in therapy workshops she ran with her husband.
The dreaming shift began after a major change in her life from cancer (which was cured) and a stroke during surgery that has limited her walking ability, but not her mind or speech. (She has written 3 books since then!) It was a very intense experience.

**So she is wondering why, and have others experienced a change in their dreams like this after a big change in their lives?  For she it feels important to her so she would love to hear from anyone else having this experience....
