I'm seeing the opposite quite often where I live, people who are quite a bit into weed usually end up needing to bake in order to sleep more comfortably.
Maybe they are having problems sleeping to begin with.
Likely, but also cannabinoids can interfere with sleep. A regular user can experience night sweats when they do not have cannabinoids, depending on frequency of use
Preferable to waking up to panic attacks from dream content.
