I hold that belief that my mind is actually a bunch of jagged triangular pieces orbiting around a single point.

That is rather disconcerting. Where did you find this information?

I've been unauthorized to use my brain's My Documents Folder. I need a password to access it but I forgot what it was. D:

Er, I mean, yeah, weird stuff.

My mind is like a vault. You need at least five ten-digit codes to access My Documents alone.

Needless to say, people read me like a book and it's not too hard to change my opinion on most subjects. =P

My mind is like this infinite white space with loads of Monsters Inc-style doors all over the place that lead to different areas of knowledge.

There's also and alternate dimension which is my dreams, which is a kind of formless mass of stuff that becomes stuff when I dream.
