To dream of a girlfriend represents personality traits or qualities we feel as consistently supportive of your success or well-being. Something you think that supports you emotionally, or regularly helps you cope with life situations. It may also reflect something in your life that makes you feel safe, or lucky. A consistently helpful situation, behavior, or coping mechanism.
Alternatively, girlfriends may symbolize our current projections of your partner or their beliefs or goals. Your feelings about them and the current state of you relationship.
To dream of a girlfriend leaving you represents the departure of helpful situations, feelings, or beliefs from your life. Habits or situations that are no longer supportive of you. Feeling something helpful turning on you or no longer working.
To dream of a girlfriend who you've never seen in real life leaving you represents new situations, habits, or beliefs that were supportive of you and no longer are.
To dream of cheating on your partner represents impulsive choices, or doing something that you can't resist. Cheating on a partner can also represent a change of current beliefs.
To dream of a partner cheating on you represents
bad choices that have consequences or dire repercussions. Turning your back on principles, integrity, or sacrifices you are making. A partner cheating on you may also symbolize your feelings about your partner having different beliefs or goals from your own.
To see a girlfriend die or murdered in a dream represents the end of a thinking pattern, habit, or life situation that made you feel good or helped you cope with life situations. It may also reflect certain beliefs, feelings, or situations associated with your girlfriend ending.
To dream of intimacy or feelings of love with a girlfriend that you don't recognize represents a new personality style, habit, or situation that is emotionally helpful for you.
To dream of having sex with your girlfriend represents positive waking life experiences where you are enjoying feeling that you can't lose. Enjoyable experiences feeling helped, successfully using your skills, or liking noticing yourself having an advantage that never stops working for you. Liking an experience where certain skills, behavior, or other people are consistently supportive of your success. Alternatively, having sex with your girlfriend may reflect enjoyable waking life situations you are experiencing with him. It could also (less likely) reflect your sex life.
Example: A man dreamed of walking down a street with his girlfriend (He was actually single). In waking life he cleverly came up with an excuse that prevented him from having to confront a difficult situation. He felt good knowing he could use the excuse anytime he wanted and it would always work for him.
Example 2: A man dreamed of his girlfriend cheating on him. In waking life he was fearing his girlfriend catching him cheating on his girlfriend. The girlfriend in the dream in this case may have reflected his feelings about his cheating behavior turning against him.
