Help Alex with his massive english essay

[Alex]

I'm looking for a book where there's a character that: exists only within another character's head, is seen as a physical presence by that character, and ideally is an important character to the book.

The point is write a nice big essay comparing it to The Beach by Alex Garland. Every suggestion would be super appreciated, even if it doesn't exactly fit what I've described above.

I know there's a book I've read with this sort of thing, but I can't fucking remember it. I'll get back to you.

Film suggestions could be Donnie Darko or even Drop Dead Fred.

I can write a book for you.

A Beautiful Mind was also technically a book first. Don't think there's much you can write about that though from an English perspective considering it's not completely fiction.

EE? Cool idea

Yeah I was totally thinking that. That'd be awesome, comparing two of my favourite books.

I (still) haven't read The Beach, so I dunno how similar it is, but it seems like the obvious choice. I dunno, I was wondering why you hadn't already thought of it, and figured there must be some obvious flaw or something. But it seems to fit your categories perfectly. Might just be a bit too common/popular/etc for EE... then again, I dunno how popular the book is.

Durr, I didn't even think of Fight Club as a book. Even though I have an entry of "all of Palahniuk" on my to read list for this summer.

Alice In Wonderland.
