Pillow
Where the head rests at night — the support that holds your thinking between days.
A pillow in a dream is the dream's image of the support your mind has during the hours it is not directing itself. The pillow holds the head when nothing else does; the dream uses it as a measure of how well-supported your interior life is. A clean, ordinary pillow is the dream telling you the rest is real and recoverable. A flat, soaked, or missing pillow is the dream noting that the place your mind goes at night is no longer holding you up — sleep is not doing its work, or the support of a particular person, room, or routine has been withdrawn.
