"To the Dreamworld" (夢の世界へ, Yume no Sekai e) is episode 427 of the Naruto: Shippūden anime.
While on the move, Tenten hopes to be able to seal the enemy with the Treasured Tools of the Sage of Six Paths she came across with, looking to find Kumogakure shinobi who can instruct her in their use. Madara's forehead plating lands on the scroll with the tools, calling her attention to the sky as the Infinite Tsukuyomi is cast. Tenten reaches for the tools as she's enveloped by the God Tree's roots. Tenten is confused as she suddenly finds herself back in her room, in Konohagakure. She goes to the streets, and is taken aback when she finds her team-mates, with different personalities from what she knows. Tenten tries eating with them at Yakiniku Q, but leaves early. She notices she doesn't recognise the Fourth Hokage's face on the Hokage Rock, and comes to the conclusion she's under genjutsu, though despite her efforts, she can't release it. She begins researching genjutsu, and ostracising her team-mates, causing them to grow concerned. Hinata takes Tenten's scroll with the weapons, demanding an explanation for her behaviour. Tenten tries taking back the scroll by force, but before things can escalate, Menma Namikaze intervenes, returning her the scroll. The commotion attracts attention of the villagers, and Tenten denounces the fake village. A merchant is intrigued by her actions.
