While Phoebe and Piper try out a love spell they find in the Book of Shadows, Prue decides to give a serious relationship with Andy a chance. Unfortunately, she attracts the unwanted attention of a wheelchair-bound man who experiments with "dream walking." Whenever this man is rejected, (which he often is due to his aggressive come-ons) he enters the woman's dreams and kills her in her sleep. This wouldn't be so terrible, except it also kills her in real life. Andy and Darryl investigate the strange string of murders, while a sleep-deprived Prue struggles to stay awake and convince her sisters that she is actually being attacked in her dreams. Finally, Prue falls asleep while driving and gets into an accident that lands her in the hospital unconscious. Her sisters are there by her side, lending their support as she battles in her dreams. In the meantime, Andy tracks down the dream culprit, and tries to have him woken up so that he can interrogate him. Prue manages to use her power in her dream so that the "dream sorcerer" dies instead of her, and Andy watches as the man dies in his sleep. Piper and Phoebe have to reverse their love spell after they gain unwanted attention from too many men, and realize that the men that they do like only return their affection because of magic.
