Summary
Will Vandom experiences a frighteningly realistic dream, and gets in trouble for sleeping in class. Her mother, thinking Heatherfield isn't working out for them, decides to transfer back to Fadden Hills. The other girls realize that they were having the same nightmares, and Will tells them about returning to Fadden Hills.

W.I.T.C.H. then decides to sabotage the transfer request, so they go Susan's building. After waiting for hours, all the girls had fallen asleep, with Taranee Cook falling asleep last. They all have nightmares, and barely wake up: Taranee learns that anything that happens in the dream happens to them in real life. She discovers that someone is invading there dreams, using their deepest fears to conjure up dream images of there imagination.

Taranee leaves to find a new way to combat the new threat while the rest of the girls take care of the transfer request. Taranee returns, and suggests lucid dreaming, making it possible to control their own dreams. They also sleep close by each other, allowing the psychic invasion to localize them all into the same dream.

In the dream they discover that it was all Nerissa Crossnic's doing, and blast her with psychic feedback to end the nightmare. After W.I.T.C.H talks to Susan about her plans and asks her to give Heatherfield another chance, and she agrees.
