"It's like we've created this joint headspace"

yes, this - sometimes my t will say something that's so out of the blue as far as what we're actually talking about, but will be something that I had been thinking about or vice-versa. One time I was sorta daydreaming during a session and envisioned a castle coming up out of the floor and surrounding her and out of the blue she mentions a dream she had about being in a castle. it blows me away every time it happens but when I point it out she just says "This is very common when two people are working so closely together."
