Can a Genjutsu awaken Mangekyou Sharingan?


It was said that Itachi's genjutsu was so good that both Kakashi and Naruto
either felt the after effects of it as if it were reality, or never even
realized in the first place that they were in a genjutsu.

So, can a strong enough genjutsu be used on someone to make them witness the
"death" of someone close to them and thus make the user under the genjutsu
awaken his or her Mangekyou Sharingan?




Not possible, Sasuke didn't awaken his Mangekyou Sharingan after being
battered by Itachi's Genjutsu. Itachi kept on replaying how he killed both
Sasuke's parents. The Mangekyou can only be awaken when the user suffer from
trauma after witnessing the death of someone close to them. With the user
normally having to witness or experience this first hand not by Genjutsu. For
further details please refer to [Mangekyo
