I must have noise to go along with going to sleep. Usually thats an audio book or long-form video essay type YouTube videos. I wear one earbud to bed if I’m sleeping at night with my girlfriend or just blare it from the TV if I’m sleeping alone during the day (rotating shift). I feel like when I don’t have engaging audio and I’m trying to sleep I can’t quiet my mind enough to sleep. A fan or random ambient noise isn’t enough for me.
That podcast sounds like the audio equivalent of Swann’s Way by Marcel Proust, where the narrator is so in his own head he spends pages going into tedious detail describing tiny facets of the most inconsequential recollections from his childhood. Highly recommended for falling asleep.
