Certain questions reguarding my theory...
Q: But what about the fetus?
A: http://www.translatedmemories.com/bookpgs/Pg112-113.jpg
Here are some explainations that could fit in...
Dahlia herself indeed possess powers such as making force fields [Good +, Bad +] repeals Cybil..
She could've materialized a fetus into Alessa.
Alessa later realizes Dahlia burnt her on purpose by the means of birthing a god, so Alessa subconsciously materializes a fetus inside her....not knowing of what shes doing.
It could be possible Alessa never had the fetus, after all, the whole events of Silent Hill seem to be in a giant projected dream world, so couldn't it just be possible Alessa just simply thought she had a god inside her?
Q: If the fetus wasn't real, then how could Alessa survive the fire?
A: Alessa was a powerful being. After the fire she is put in a coma like state, what could be possible is that Alessa is projecting her mind/spirit out of her body and placing a partial part of her soul/mind into the cemetary [Cheryl] and so after splitting her mind, her powers are decreased but Alessa is still powerful non the less..
Cheryl could simply be a incarnated delusion with half of Alessa's Mind/Soul, just like how Alessa is able to manifest into a god-like creature and be able to project monsters. What is also possible is, if Alessa's full soul/mind were to return back into the body, Alessa could possibly die, this may sound strange, but it's like, shes subconciously trying to escape the reality of death. If half her mind/soul is gone, her process of dieing is stalled...[ you know how in SH1, after the soul is combined with Alessa's body, and you don't have any ammo...you can just simply run around until the boss dies, why not any other boss?], Alessa will materialize an incarnated delusion of a child again and places [atleast somewhat of her soul inside the child (Cheryl that Harry kept pleading to Alessa perhaps..) and after Alessa herself finally dies from the fire (why do you think burning meteors fall? Alessa is dieing and losing grip on her dream, she is dieing from her burns and bullet wounds (if you did attack her with a gun), but mostly the buring wounds so she is dreaming of getting killed by flaming meteors while in real-life she is finally dieing from her burns (Example, ever have dreams were your *ahem* "using the bathroom" and you wake up with "wet pants....", this is how im comparing the flaming meteors and her life burnt self) and it's not for sure but perhaps that part of Alessa's mind dies or trails off into the body of Heather (but if part of Alessa dies in Silent Hill, it would makes sense why you battle memory of Alessa in SH3)]
We don't really know for sure when Alessa wakes up from her coma but we do know she does because she associates with Lisa, Lisa gave her a diary. She also knows Michael Kaufmann [In the play novel (Dairy) says she didn't really like him but she heard Kaufmann act concerned and worried for Alessa's status.].
