Dream Lovers — Ronnie G. Anderson

Dream Lovers (78,401 words) Take one pair of ghosts returning to the old building where for years they had continued a torrid love affair of adultery only to find out that they do not have living bodies to love one another with anymore. That's really no problem since they can possess other people's bodies and feel what they feel; so it is that the old man inhabits an actor who appears to be a raging homosexual in his dreams and couples with the three sisters living across the hallway from him. Of course the real humans think that they are in a dream and that they are different people. When after a while the three sisters all turn up pregnant - well, matters get more complicated!
