Interesting theory. I feel as though they may be similar, but are altered because of how things transpired after the timeline split. For that reason, they aren't the same, but are similar.

Silent Realm is the Sacred Realm I mean they are both mirror images of Hyrule with strong connections to the Triforce
The Silent Realm was a dimension created for Hylia's chosen hero - Link - to be tested. The Silent Realm is hardly connected to the Triforce until you reach Skyloft's. The spoils obtained by defeating the first three took you to the next dungeon's entrance. From there, you would do whatever was required in there - obtain the item, defeat any bosses in there, etc. - and then obtain the next song. It wasn't until Skyloft's that it had nearly nothing to do with the Triforce.
The Sacred Realm however, was made to house the Triforce. If you recall, in
Skyward Sword, the Triforce wasn't even housed in a realm of any sort. If the Silent Realm and the Sacred Realm were the same thing, then your prize for completing Skyloft's Silent Realm would have been the Triforce.
And then of course there is the Twilight Realm which Ganon was sealed in and where Link turns into a wolf(bunny?).
Ganon was sealed in the Twilight Realm? Don't really remember where they said he was imprisoned. I'll take your word for it on that one, I suppose. Now, it's hard to really disprove the wolf/bunny relationship. I can see where you're coming from with that one. However, Link in
A Link to the Past was turned into a bunny because it was considered to be his true form. I don't recall them explaining why he became a wolf in
Twilight Princess. I'm going to assume it's because it's his true form, just for the sake of this theory.
And a lot of people say that the Twilight and Sacred realms can't be the same because they wouldn't imprison Ganondorf in the Sacred Realm. Well then explain to me a Link To the Past.
Weren't the Dark Interlopers sent to the Sacred Realm as punishment, or something along that line? Anyway, Ganondorf Dragmire willingly went to the Sacred Realm to claim the Triforce; that's not imprisonment. I compare that to the people in
Silent Hill;[/I they willingly go into that realm in order to find something they want.
I think that your points show that it's possible for them to be similar, but not the same. You see how the scenarios change; instead of willingly going to the Sacred Realm in A Link to the Past, Ganondorf is imprisoned in the Twilight Realm - which seems to be a Twili-based Dark World - in Twilight Princess. Instead of his true form being a bunny in A Link to the Past, Link's true form is a wolf in Twilight Princess.
It seems like the timeline has had a larger effect than we originally thought; it doesn't just affect what happens to Hyrule, but also what happens to the Sacred Realm; does it become the Twilight Realm, or the Dark World?
