Because your subconscious mind controls the way you sleep with your partner, sleep body language can be an amazingly accurate way to assess what's going on in your relationship even if you can't or don't articulate those things while you're awake, says Patti Wood, a body language expert.

Back to back
Sleeping back to back, but with intimate physical contact is one of the favourite positions for most couples because it gives them space while keeping them in touch with each other. This position is symbolic of a high level of security and comfort between the partners. There is usually a relaxed camaraderie, and a sense of equality between couples who sleep this way. Couples develop this style over the years once they are fully comfortable with their independence and interdependence.

The classic romantic embrace, spooning portrays a relationship dynamic in which one partner takes a protective stance over the other. It involves trust, experts say, and is often a sign that all is well in the bedroom.

The honeymoon hug
In this position you two are facing each other, while hugging, you just want to become physically one. This reveals passion and a desire for each other, also known as the lover's knot, this is more common when the couple has recently started sharing a bed and are too hot for each other.

An attempt to focus total attention on a partner, even in sleep. Whoever's head rests on the others shoulder is the more dependent and compliant partner. Or just shorter.

It signifies trust, allowing for more space and comfort without sacrificing affection. Ultimately, this position represents balance.

The sweetheart hug
If the cuddly sweetheart pose is your favourite, it shows that you two are true romantic souls. It is a nurturing pose, which also indicates the dominance of the male partner, since he takes his woman under his wing in a protective gesture.

The leg hug
If your partner plays footsie with you in bed, or intertwines their legs with yours, it means they crave an emotional or sexual connection.
