The language in your dreams switches to Japanese.

When you watch the machine girl and crave for more.

I've had that a few times, not a lot of spoken stuff but definitely Japanese.  I also have dreamt in subtitles after watching far too much anime one day.. now that was odd.

There's are so many things in this thread that are happening to me x_x

I forget common English words (especially spelling!). My thoughts immediately translate to Japanese, and I feel compelled to look up a word if my thoughts can't translate. My reading speed in Japanese is getting faster while my speed in English is actually getting slower. I don't remember my dreams often, but the few I can remember I remember at least mostly being in Japanese (usually I'm in Japan).

A thousand times this.  I misread things that look like they could be romaji all the time as well.

Another thing that happens to me (especially if I'm tired/been drinking) is if somebody asks me something suddenly vocabulary related ("What do you call a <blah>" "How do you say/pronounce <blah>") that I'll sometimes grab the word from the wrong language.

#5- You start looking around for the Tabasco sauce and feel relieved there is no corn or eggs on your pizza.
#4- You check first to see if there is beef curry in your donuts
#3- You get irritated when there are no Kirin vending machines outside the local liquor store
#2- Pet Sweat sounds like something nice to drink on a hot day
#1- You have to think for a second how to pronounce the letter L in Engrish.

Instead of saying What? you say あれっ？ or when you get up out of a chair and say よしゃっ！

When you start speaking Japanese to your English-speaking friends. Bonus points if you don't realize it until your friends ask what language you are speaking.
