Dimension in Naruto where they get stabbed forever I remember this one episode in Naruto when I was a kid, where Naruto's instructor, who had the cloth over one of his eyes throughout most of the series, looked into this one enemy's eyes and got teleported to a dimension where time passed really slowly. The person who he looked into the eyes of was there with tons of clones just repeatedly stabbing him with katanas.

I apologize for my lack of knowledge in the subject concerning names, but I vividly remember this one scene and I'd like to know more about it.
The character who did that was Itachi, Sasuke's brother.

The name of the move was Tsukuyomi.
