If she looks up to her left (observer's right-- as in this picture), this indicates she is thinking mental pictures about the PAST. (Maybe she is recalling last night!)
These eye movement patterns are done naturally by nearly everyone who thinks with mental pictures. (Some small number of people think in sounds and some with feelings.) Of course if you plan to use this in flirting, you should enhance your eyes with an abundance of eye mascara, eye shadow and perfectly shaped healthy eye brows. This body language eye movement when done slowly and with a coy head tilt can greatly stimulate a man. It is an art form that the best flirters develop to a highly effective level.
