Blue Pillow in dreams
Where the head rests at night — the support that holds your thinking between days.
How blue changes the reading
Blue colour cools the symbol — calm, distance, the steady side of the spectrum. Whatever the base meaning, blue says the situation is operating at a temperature you can think in.
The base reading of Pillow
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longer holding you up — sleep is not doing its work, or the support of a particular person, room, or routine has been withdrawn.
