What you're suggesting is grammatically impossible in English. If what you're suggesting would have been true it would have said: "Dracula's false castle". For example, you say "Dracula's large castle", not "Large Dracula's castle". 
Its not a suggestion, its indeed what is written in this page. a "'s" after something means that its talking about something owned by this person.
I don't think that's correct. It's explained very well here: http://www.oocities.org/nec43xkq3/hod/index.html
Okay, even so its Dracula, a incomplete Dracula like I've said earlier. Also its not a official explation, but even so Im not discarding it.
I don't think so. Rembember, it's the worst ending we're talking about, and it only appears when your playtime is ridiculously long... I strongly doubt it was intended as a "teaser" for a next game.
If anything, it would have meant: "see you again" in a different playthrough of the game, where you'll probably try, well, not to take as long.
Please, re-read it or go read it in bisqwit's website, this message only appears on the best ending and isnt related to a variable flag, only the hand is.
Now, you've given me the first part of the ending dialogue, but not the rest. Here's what happens after the battle.
Sorry thats not my intention, I've only pasted everything that I've seen, I forgot about the dialogue that happens after that. Even so Simon Wraith is named Shimon in the japanese version IIRC correctly, me or someone else would need to check that. While Shimon is meant to be a pun, Dracula isnt.
I don't think that's the case here. Note that the bright blue colors of daytime seem far more joyful, and far more indicative of a "best" ending than the darker, orange tinge of dusk. Now, I don't believe the worst ending is there as a "black and white photo". Remember, the endings depend on how long you take to complete the game. So here's how they should have been ordered:
The worst ending: Night
The good ending: Dusk
The best ending: Daytime
See? Doesn't that make more sense? And yet that's not how it's done in the game...
This doesnt seem to change anything, since the game itself doesnt happens in one day only. Even so I compliment you because this explanation is very good.
Sure. But the Dracula Wraith didn't exist until about one year before HoD's events. Therefore, it's impossible for Dracula's hand from CVII to be the Dracula Wraith. Trust me, I considered that possibility before. 
Sure, because no one found it until then. Only because they dont discovered something yet, doesnt means that it doesnt exists. We only need to take a look in HoD to see that Dracula was in a very weak state.
Actually, Inccubus linked to an alternate translation by another person who translated it the same way as Koutei and JPCVFAN. It's the same guy who translated the game's dialogue, so you can't say his English is also insufficient. 
Well, we should need to check that, I've noticed that his translation in Finnish have some puns adapted while its left out in the English version, being a translation without adapting the joke. This shows that maybe he had some difficulty to translate it, so while its very well translated maybe something could've slipped.
That's impossible because Simon could only break the curse until he burned all body parts. Dracula bursts into flames when you defeat him, so I assume that Simon burned the final body part at that moment and then broke the curse.
Are you being serious? Almost all enemies burns when they die in a Castlevania game, its really difficult to say it now, since we dont know if self-combustion still counts.

But remember that Dracula would return when the curse kills Simon, here he returned before that, maybe the curse was broken because Dracula has been defeated?
Also try to dont take it personally, but you are trying to act like some old user using "impossible" in almost every response. Only wanted to point your that since I've never seen you act like that before, so if someone is hurting you in some way is better to talk with this user instead of holding this grudge and acting like that.
