Long fingernails signify difficulties with the opposite sex; short ones predict an unexpected gift. To polish (or varnish) your nails is a warning against impulsive behavior that could lead to a scandal. To painfully bend back or damage a nail indicates a rather long season of discontent. To cut your fingernails signifies achievement in prestige; to file your nails signifies achievement through your own efforts. If you dreamed of biting your nails or of nails bitten to the quick, you may want to consider getting a medical checkup.
