What does it mean to dream about an intercourse?
The interpretation of this dream depends on the details.
If you were personally involved and you enjoyed the experience, it is, obviously, an omen of happy adjustment to your circumstances.
If your dream featured others having intercourse, the meaning relates to whether or not your reactions were unpleasant.
If they were, it is likely you are repressing an emotional problem and some psychological counselling might prove beneficial; if they were not, contentment and success will soon be yours.
