Dream about getting bitten by a rat stands for your attitudes with death and your sense of mortality. Someone is trying to force their opinion or view on you. You are feeling restricted, confined and restrained in a current relationship or business deal. It is an evidence for missed chances, missed opportunities, or missed judgment calls. A situation is making you too tense.
Getting bitten by a rat dream is a signal for someone in your life whose charm may ultimately prove harmful. You may feel that time is running out in a business or personal matter. You may be feeling emotionally dirty or guilty and are trying to wash away the shame. Your dream is an alert for your tendency to keep your thoughts, ideas or feelings inside instead of expressing them. You are looking for romance, excitement and freshness that is lacking in your present relationship.
If you dreamt about getting bitten by a rat:
You could try, but with your propensity for tactlessness, you may well get yourself into even more trouble. Your love interest may be pressuring you into giving some kind of response or explanation, but it would be better if you could put this off until you have an answer.
