People tend to think that sex dreams reveal hidden desires which come out when we are sleeping. But, it seems that there is a quite different explanation of our weird sex dreams.

Expert dream analyst Kelly Sullivan Walden decodes and explains the most common sex dreams in a new book called The Love, Sex, and Relationship Dream Dictionary.

So, here’s what some of the most common weird sex dreams actually mean. If you dream of having sex with:

Your Boss
A boss typically represents authority, and this dream is giving you a sense of your own empowerment. It means you’re looking to “be the boss” in your own life.

A celebrity
Having dream sex with a celeb means you want to step into the spotlight and change the world.

An Ex
An ex represents an aspect of yourself that you may have been in touch with when you were with that person, that maybe you don’t seem to have right now.

An animal
This dream is all about a desire to reconnect with your ‘animal instincts’ and get away from technology.

An alien
Alien-related sex dreams mean you want to embrace the quirks that make you weird – or ‘alien’.
