Sexual dreams are very clear representations of a strong desire for something. Often the dream can be a straightforward desire for the person you see yourself having sex with but there may be other signs in the dream that can be read.
The type of sex you are having with the person can indicate a power struggle in your relationship; if you are being dominated by the other person this shows that you are feeling uncertain and want the other
person to make the decisions; if you are the one doing the dominating it shows that you want to be in control and feel threatened by other people telling you what to do. Sex between two equals can show an alliance between two friends, or it can indicate that you both get something out of the relationship.

If you don’t know the person you are having sex with, this shows that you are looking for an adventure or are bored with an aspect of your current life and looking for a change. If the person you are having sex with is a celebrity or someone famous this shows that you are looking for acceptance from those around you.
If you are having sex with someone of the same sex but are not homosexual this shows that you are feeling bored in your own relationships and are looking for a bit of excitement.

If you are having sex with someone of the opposite sex and you are homosexual this shows a fear of not being accepted and a sign that you want to fit in.

If you are not one of the people having sex in the dream, this represents your sense of insecurity – you don’t think that you are important enough to be the main actor in the dream.

If there are more than 2 people having sex this shows that you are feeling overwhelmed by emotion and passionate thoughts or that you have a big decision to make. Toys or other objects that are being used in the dream can indicate that you are relying on someone or something else to help you come to your decision.

If in your dream you are having illicit sex, sex with animals or someone you shouldn’t be having sex with this can be a sign that you have done something in your real life which is making you feel guilty and you are worried about people finding out.
Sex outdoors can be a reflection on your need to do something different, break the mould and bring a little adventure into your life.
