Hi 55171!
I went to dreammoods.com and looked up milk.
Seeing it indicates maternal instincts and motherly love!
Sounds very appropriate to me.
Why you in a coffin?
Perhaps because at that time your response to her affections
are unknown. I get impressions, like sleeping beauty or snow white,
not really dead, just waiting for love to awaken her.
Hope this helps.
Marj
