At first glance, this position looks exactly like spooning, but take note of the location this couple are in on the bed. When one person has relocated to the edge of the bed, with the other one "pursuing" them, it's referred to as the chase. The origins of the name are certainly very obvious! But what does this mean for couples who sleep in this position?
One theory about the chase position is that the person who is being chased enjoys being pursued. They are engaging in the sleep version of 'playing hard to get' and love that their partner continues to seek them out and hold them during the night. While it all makes sense when you read it, it's hard to imagine that we're really thinking hard or playing mind games when we're asleep.
