The way couples sleep together can unconsciously reveal how strongly they feel for each other. Just as sleep restores used powers in ones body, sleeping together will also revitalize the relationship. Although there are some factors that may disturb the calmness of this method, such as the snoring or teeth grinding etc., at least the issue of faking out can never be a part of it - since there is no way you can deliberately mislead someone when you're completely asleep.
When in a situation where both you and your partner don't agree with each other's way of sleeping, find a way to consider. For example, if you think your partner is a bed hog or is maybe moving too much, get twin beds. In that way you both will have your own spaces and still sleep together. So there you go, try to experiment and find a way to compromise. It is always the best method to bring two different minds together and make ends meet.
