The novel experiences explanation is very interesting but I'd wonder whether novel ideas constitute experiences, or are experiences something that requires more action or something else? Anecdotally, I've been sitting in the same house for 20 months of the pandemic and have a diminished sense of time, and while in that time I've taken up music and new instruments, written volumes, transformed physically (weight loss), kept up regular highly intense physical hobbies, added and removed clients/jobs, worked in vastly different fields. However, I've always pursued novelty, and I'd wonder if this accepted explanation would indicate that the brain is now just bored of novelty, or if something about these things were not sufficiently novel experiences, and where does that sufficiency land?
