After performing a powerful spell to defeat Adam, Buffy and the gang relax by having a quiet night in front of the television. Falling asleep Willow, Xander, Giles and Buffy each have strange dreams where they are stalked by a primitive force that may be related to the spell they performed.
The dreams sequences are very well done and are packed with interesting details and plot foreshadowing. The episode captures perfectly a sense of surreal dream logic while still being coherent enough to be totally engrossing.
The episode delves into the slayer mythology and includes plenty of references to past episodes.
The cast are all excellent, the directing is perfect and special mention must be made of the wonderful musical score that is suitably mysterious.
One of my favourite episodes, there are so many memorable moments I never get sick of rewatching Restless.
