Buffy vs Dracula:
1. Olivia’s pregnancy in Giles’ dream may signify the coming of Dawn. Giles became a father figure to Buffy’s sister.
2. Tara says “Be back before Dawn.” This is a reference to Buffy’s younger sister Dawn who made her debut in the very next episode. (Thanks to Daro).
3. Tara also says “You think you know…what you are … what’s to come. You haven’t even begun.” In the season five opener, Dracula repeats this to Buffy.
4. In Giles’s dream, Buffy is at a stall at a fun-fair where she is trying to knock down a puppet called ‘Count Drac’. In the next episode, her opponent is Count Dracula.

The Replacement:
Buffy dreams that she’s was sleeping in her dorm room bed then ‘wakes up’ in her bed at her family house. In the next season, she leaves the dorm to move back home.

Family:
Tara tells Willow she doesn’t know everything about her. In season five’s Family we discover Tara has been hiding a secret that she believes she’s a demon of some kind.

Into the Woods:
Buffy dreams that Riley says to her, “I thought you were looking for your friends. Fine, if that’s the way you want it, you’re on your own, killer.” Riley leaves Buffy in the episode Into the Woods.

The Gift:
The number 730 returns from Graduation Day (Part 2). At that point, the number signified the numbers of days before Buffy died in season five’s The Gift. Here, Buffy sees a clock saying 7:30 and Tara says that the clock is wrong. This means that there are no longer 730 days before Buffy’s death.

Bargaining (Part 1):
Giles dreams that he must choose between Buffy, who represents Sunnydale and Olivia, who represents his life in England. He chooses England in season six.

Once More, With Feeling:
In Willow’s dream, Giles says “Stay in character…especially in the musical numbers!” There is of course the musical episode in season six.

Tabula Rasa:
1. Spike wears tweed like Giles’ in Xander’s dream. Giles says he’s teaching Spike to be just like him. “Spike’s like a son to me.” Spike wears the tweed again in Tabula Rasa and, after losing his memory, believes Giles is his father.
2. Xander says, “Like a shark with feet and … much less fins”, Spike then added, “And on land!” In Tabula Rasa the bad guy is a literal “loan shark” who is a shark who walks on land and has fins. (Thanks to Chip)

Hell’s Bells:
Xander’s father yells, “What the hell is wrong with you? You won’t come upstairs? What are you … ashamed of us? Your mother’s crying her guts out!” In Hell’s Bells, Xander leaves Anya at the altar, scared he will become a terrible husband like his father. His mother cries in that episode.

Entropy:
Anya says, “I’ve been thinking about getting back into vengeance.” She does, and we see the effects in season six’s Entropy.

Lessons:
Snyder says to Xander, “I walked by your guidance counsellor’s office one time. A bunch of you were sitting there … waiting to be shepherded.” Buffy becomes a guidance counsellor at the school in season seven’s Lessons, and for a few episodes there after. Snyder’s remarks probably signify how Xander feels about Buffy’s role as leader of the Scoobies.

Get It Done:
1. Buffy meets the First Slayer in a desert. She’s back in the same desert with the Shadowmen in Get It Done.
2. When Buffy dreams that she wakes up, she sees the First Slayer chained to the ceiling. In Get It Done, we learn that Shadowmen ‘made’ the first Slayer by chaining her to the ground.
3. Buffy tells Adam “We’re not demons.” She discovers in Get It Done that the first Slayer was made by being given a demon’s heart. Relating to this, Adam says to Buffy in Restless, “Aggression is a natural human tendency, although you and me come by it a different way.”
4. Giles says to Spike, “I still think Buffy should have killed you.” He hopes this again most obviously in season seven, when he sets Spike up to be killed by Principal Wood.
5. The bag from which Buffy gets the mud is actually given to her in reality by Principal Wood in Get It Done.

Storyteller:
In Giles’s dream, he sees Spike having his picture taken in different intimidating poses. In Storyteller, when Andrew is recording Spike for his documentary, Spike is seen being filmed (”Sod off before I rip your throat out and eat it”), and is willing to repeat the recording when Andrew tells him that the light was in the wrong place. He is acting intimidating and scary for the Andrew’s camera, just as he was acting for the cameras in Restless.

Chosen:
The First Slayer tells Buffy that as a Slayer she’ll always be alone. These words are said again in season seven’s finale Chosen and trigger Buffy’s idea of how to attack the First’s army.
