I had not slept with many men other than my husband, but I noticed before that to sleep, actually sleep with someone did give this sense of intimacy, as though your dreams had flowed out of you to mingle with his and fold you both in a blanket of unconsciousness knowing. A throwback of some kind, I thought. In older, more primitive times, it was an act of trust to sleep in the presence of another person. If the trust was mutual, simple sleep could bring you closer together than the joining of bodies.
