Dream about the girl you like with another guy is a harbinger for wholeness and the circle of life. You are looking back at past emotions and what you can learn from those experiences. You can restore your faith, optimism and hope. It is a portent for the importance of spiritual enlightenment and inner strength as opposed to material richness. You need to stay the course and continue to move forward.
The girl you like with another guy dream is a premonition for the dualities of your personality - the persona you show to the world and your true Self. You are feeling stimulated mentally. You are feeling productive and optimistic about some new project. This dream is an indication for strength, responsibility and burdens. You are feeling neglected.
If you dreamt about the girl you like with another guy:
Newspapers, books, and TV are apt to bring a lot of new, exciting, and useful information your way. This might set your mind going in such a direction as to bring new ideas for projects or business opportunities your way. Discussions with others who share your interests could contribute even more. Expect an exciting and stimulating day, and by day's end you're likely to have opened up new doors for yourself.
