Take this with a grain of alt because sleeping is my superpower usually, but lately I've been running one of those 8 hour relax loops on youtube (mindAmend is the channel I'm using most - IDK about the actual life changes benefits of isochronic tones and the rest but I find his stuff restful) and when I wake up, I find my mind latches on the noise goes, ah yeah that's that music and just settles back down.
