Cryptic words

The other night, I awoke in the wee hours of the morning having been having some sort of dream. And there was this insistent phrase stuck in my mind. So I stumbled out of bed, jotted it down on a piece of scrap-paper, and went back to sleep. When I awoke up, any and all details of this dream were gone; I didn't even remember having written anything down until I happened to see the note. I had written:

"A pathology of cream-filled hatred"

Any insights on what this may signify are appreciated.
