Here are some potential clues to start you off:
Try to think deeply and be honest with yourself. Don’t suppress your fears or insecurities. You won’t be helping yourself by doing so. It’s surprising what dream interpretation can reveal, if you only give it the time and respect it deserves.
Only one thing is certain.
If you dream about somebody, there is always a reason. It might be a trivial reason such as simple lust, or a more complex reason such as unresolved emotional issues.
But there is always a reason.
You probably just came by wondering what your dream meant, but why not learn how to control your dreams whilst you're here?
Once you learn how, you can actually interact with these dream figures and ask them yourself why they are in your dream!
