Again we go back to the databook statement of Tsukiyomi:
"Within the Sharingan's telepathic and hypnotical powers, the greatest genjutsu was created out of hypnosis: Tsukuyomi. On this earth, people are subject to things like time, gravity and air, and the people who can maximize their abilities are the ones who decide who is the winner and loser. However, Tsukuyomi gives the user the ability to drag his opponent to an imaginary world that the user builds, and restricts him in it.
Common sense does not apply in this imaginary world like it does in the real world. There is no possibilty of dispelling this genjutsu. People caught in this genjutsu do not know when this imaginary world will end, and the user controls everything. He shows them the punishment of hell. It makes the person caught in it crazy. Even if you are strong enough to break rocks, or fast as lightning, it matters not before this technique....that's why this technique is feared."
This is one of the things that seperates Tsukiyomi from regular genjutsu. In all genjutsu, they all need to make contact, one way or another to affect their opponent in genjutsu, like how frogsong required the waves to reach the ear, etc. All tsukiyomi needs is is the sharingan hypnosis, then it uses its 'telepathic powers' as its stated in the databook.
