No and no. This can't be the Dream World since Doremy would have found and kicked me out of it already, and I've never heard of Subcon.

[Though there is one other problem.]

I don't actually know this world's name... so let's suffice it to say that you fell through a sort of hole in reality and this is where you ended up. Same thing happened to me a couple months ago. Aya Shameimaru, fastest news in Gensokyo, pleasure to meet you.
