For non-native English Speakers

I don't really understand what one mean by "what language I think in", as I don't think in any language. I can't seem to wrap my head around someone saying "I think in English", as English is a language, not thinking! This also yields in dreams.

When you're talking with someone and want to express something, in order to make word a phrase correctly, I'll obviously "think" in the language we're talking about.

As for the language my family speak, it's either Dutch, Norwegian or German depending on which part of the family.

Here's a test!

Try learning a new language. Then as you first begin to speak/write, I find you'll most likely translate in your head a preconceived sentance in the language of your brain! Thought I guess it's also just the same as the language you're most comfortable in, like whatever language you use when you talk to your self/ remind yourself of things.

I do see your point though, just seems very philosophical =P

I defintely think in english, and have for as long as I can remember despite it not being my mother tongue.
