I think in English and speak both. I stopped thinking in Indonesian due to an accident almost a decade ago now. It has been a topic I am hugely interested in because our brain is mysterious and I am one of those examples of how a brain injury could alter the way we perceive and speak.
So far, I don't swap at all and even in my dreams, it is not in Indonesian anymore and I have a lot of tip of the tongue moment when it comes to Indonesian 😄 and I am definitely slower if I were to learn things in Bahasa Indonesia than English.
Very interesting indeed! Thank you for sharing your response, it is appreciated and a great insight into what makes you, you, and in a tiny way, perhaps what makes us all so interesting as individuals. It is all the variance.
Indeed, it's fascinating how human can be!
