Grey Puppy litter in dreams
A group of newborn puppies — uncomplicated affection and many demands at once.
How grey changes the reading
Grey colour layers ambiguity onto the symbol. The base meaning is still there, but the dream is saying you do not yet have the colour information — the situation has not declared itself.
The base reading of Puppy litter
A litter of puppies in a dream is the dream's image of a lot of simple love arriving in one place. Puppies are entirely demanding and entirely uncomplicated; the dream brings the litter when there is a wave of affection — given to you, or asked of you — that is straightforward but not small. A litter of puppies climbing on the dreamer is the dream affirming that the love is real and the demand is manageable. A litter neglected in a corner is the dream noting that affection has been arriving and you have not been present to receive it.
