Rutherford - The cloudy blue water - I have to go with past experience with this - suggests that not everything from the toilet is filthy. Sometimes the blue - something transcending ones own small life - comes from the most unexpected sources.
A quote from a poem -
“And as I stood
Letting my water cascade
Into the eager bowl,
A flood of green blue light
Flowed upwards to me
From the pool’s depths,
Washing over me like
Music, like liquid light,
Engulfing and penetrating me.
It touched me as softly
As a mist, healing me.
That so much tender beauty
Should shine from a place
So long thought unclean,
Was all the more wondrous
And felt.”
Your dream also has much of what you received from your mother and father in it. The white nightgown, obviously memories from the past because=se your parents then appear in the room with you, suggesting a present impression.
The purity of the nightgown which is again a reminder of transcending ones own small life, is then leading you to the picture of a graveyard, a message from your father.
Your parents represent all the thousands of memories and lessons you have within you from them. See
http://dreamhawk.com/dream-encyclopedia/the-conjuring-trick/ You have taken in millions of bit of memory, lessons learnt, life experiences along with all the feelings or problems met by loving and living with someone and they are what makes you the person you are. The memories and experience we gather unconsciously change us and are not lost. It is part of you and is symbolised in dreams as a person or event.
The picture if the graveyard is just that - a picture - perhaps a reminder of death that your parents will face eventually and they wished to slowly ready you for it.
So in the unusual state of awareness you were reminded of death - a picture kept near to your heart.
