Rat dreams arrive with a shudder attached; many people wake from one feeling less frightened than contaminated. Yet the Golden Wheel and Miller were not horrified by the rat. They read it as something more ordinary and more useful: the hidden thief, the loss or the false friend working unseen, in the walls, behind the stores, just past the light.
| Variant | What the old books read | Source |

| Many rats (or mice) | Thieves in the house; many mice at play, joy | Golden Wheel 1862; Artemidorus |
| Hearing rats gnaw | A loss by robbery in one's own house | Golden Wheel 1862 |
| Killing a rat | Victory in any contest; a thief caught | Miller 1901; Golden Wheel 1862 |
| Catching a rat | Outstripping one's enemies | Miller 1901 |
| A rat trap | Being robbed; an empty trap, freedom from slander | Miller 1901 |
What does it mean to dream about rats?
The Golden Wheel Dream-Book (1862) was direct: "To dream of rats is a sign that thieves are around," and it read seeing them as a friend being robbed. It even warned a girl who dreamed of rats not to let her lover take liberties, lest he rob her of what could not be restored. Miller's 1901 dream dictionary (Ten Thousand Dreams Interpreted) moved the thief next door: rats meant being deceived and injured by one's neighbours, with quarrels among companions.
Artemidorus, whose Oneirocritica (2nd century) we cite in Friedrich Krauss's 1881 German translation, has no rat at all. He read the mouse, and read it as a member of the household, since it lives in the same house and eats the same food. That gives him a different view of the swarm, below.
The books agree on the method: the rat is someone close, taking something quietly. Miller and the Golden Wheel both brighten when the dreamer fights back. Where the snake is an enemy you can at least see coiled in front of you, the rat is the one you only hear.
Where they were, and how many
These are readings from the old dream books, reported as history — no dream foretells the future.
What does it mean to dream of rats in the house?

Scratching in the ceiling, a shape along the skirting board, droppings in the pantry. None of the three books has an entry for rats indoors as such, though the Golden Wheel's gnawing rats below come close. The modern reading follows the geography: the worry isn't out in the world somewhere, it's living where you live, in the household, the accounts or a close relationship.

What does it mean to dream of many rats?

A floor that moves, a pack pouring from a drain. The Golden Wheel Dream-Book (1862) sent its rat reader to its mouse entry, which read seeing a number of mice as thieves soon in the house. Artemidorus, writing of mice rather than rats, disagreed: many mice playing merrily announced great joy and more servants in the household. The modern ear hears small worries multiplying, each easy to dismiss, together taking up the house.
What does it mean to dream of just one rat?
A single rat walks into the middle of the floor and looks at you. None of the three books reads a lone rat. Psychologists would call it strangely good news: a rat that has stopped working in the walls is a worry that has surfaced where it can finally be named. The dream has done half the naming for you; the other half happens awake.
What the rats did
What does it mean to dream of a rat biting you?
A sharp nip at the hand or ankle, often remembered in the body on waking. None of the three books reads a rat bite. The modern reading is contact: the quiet worry has stopped hiding and made itself felt, often through a person or a bill you can no longer ignore. Where it bit, and whether you pulled away or held on, usually says more than the bite.

What does it mean to dream of hearing rats gnawing?
You can't see them, only hear the gnawing behind the wall. The Golden Wheel Dream-Book (1862) made a fine distinction here: seeing rats meant a friend would be robbed, but hearing them gnaw meant the dreamer's own household would suffer a loss by robbery. Psychologists hear the same thing in modern terms: a worry you can't locate, only hear, working steadily at something you value.
What does it mean to dream of a dead rat?
A dead rat under the sink, or on the doorstep. None of the three books has an entry for it. The modern reading is mixed: a trouble ended, but its traces still to be cleared, the smell that lingers after a problem is technically solved. How you felt on finding it, relief or disgust, usually decides which half matters.
What you did
What does it mean to dream of killing a rat?
The rat cornered, and dealt with. Miller's 1901 dream dictionary was brief and bright: "To kill one, denotes your victory in any contest," and in his "Mice" entry read killing mice as conquering one's enemies. The Golden Wheel Dream-Book (1862), through its mouse entry, read killing one as catching a thief in the act. Psychologists read the dream as rehearsal: naming and confronting the thing that has been gnawing.

What does it mean to dream of catching a rat?
Not killed, but caught, alive in a box or by the tail. Miller's 1901 dream dictionary read catching rats as the dreamer scorning the baseness of others and worthily outstripping their enemies. Letting mice escape, in the same dictionary, he read as doubtful struggles. The modern reading is control without cruelty: a problem contained, held where you can look at it.
What does it mean to dream of a rat trap?
The spring, the bait, the snap. Miller's 1901 dream dictionary read the trap every way it could fall: falling into one yourself meant being victimised and robbed of something valuable; an empty trap, freedom from slander or competition; a broken one, being rid of unpleasant company; setting one, learning of enemies' designs in time to outwit them. Psychologists ask who set the trap, and for whom.
What does a rat dream mean psychologically?
The modern reading keeps the walls and drops the superstition. Rat dreams tend to accompany something eating quietly at the dreamer: a shame, a debt, a doubt working in the walls. And psychologists reframe the ugliest part of the dream kindly: the disgust usually points at how you feel about the worry, not about yourself. You are not the rat. The rat is the thing you haven't looked at directly.
The Golden Wheel's and Miller's instinct survives here too. They read the rat as someone close taking something quietly; the modern reading moves the thief inside, to the worry that takes your attention, your sleep, your patience, a little at a time. Naming the gnawed thing by day tends to quiet the walls at night.
A question to sit with
What in your waking life is being quietly eaten, a sum, a confidence, a store of patience, that you rarely check on, because checking would make it real?
The Golden Wheel heard thieves in the gnawing; what you hear is your own. No book could tell you that your rats appear in your childhood kitchen, or only in the weeks when a certain bill goes unopened. The pattern is the message, and patterns take more than one remembered dream. It's what Dreamlock, on the App Store for iPhone, is built for: it listens to the dream you record, paints it, and shows you over time what your rat runs alongside.
