Since I'm getting old, I don't remember the first time I started to have dreams in languages other than English. Suffice it to say that is was a very long time ago. If I were to guess, I would say I was probably in high school. For a year in high school, thanks to an exchange student from Ankara who arrived only being able to speak Turkish and French, and another exchange student from Northern France, I spoke French just about every day. In fact, it was awhile before I bothered speaking English to these particular students... after all, they had to learn enough of it first to be conversant, and though my French was certainly not good, it was good enough that I could have a conversation... ah, but I am off topic. The topic is dreams.
I love so much about this song by the way. The bass slides in the turnaround after the first chorus, yes. The subtle distorted guitar that comes and goes, which I especially like in the second verse. That arpeggio that plays during the verses. The strings. The way the feel of agitation grows, then releases. Thom's falsetto.
I don't personally have very many dreams that I would categorize as "nice", but usually when I do, there is plenty of non-English dialogue involved. It's probably normal for people in our lives to show up in our dreams, and there are plenty of people in my life for whom English is not their native language. For my dear friends who speak French (like people I write songs about), when they show up in my dreams, they show up speaking French. For the people I know who speak Spanish, when there is a conversation with them during a dream, it's in Spanish.
Here's what I wish were a thing: I wish there was a way to record this stuff. See, I wonder if my pronunciation and grammar and whatnot is better in dreams than it is in real life. I feel like it very well might be, as the conscious brain just gets in the way sometimes, you know?
