Is this narcolepsy?

I don’t have any experience with sleep disorders but by SO won’t wake up unless I wake him up. On his days off he goes to bed at like 9:30 and wakes up at noon, only if I wake him up and say its noon.

I can’t tell if he has a sleep disorder or just lazy because he also hides in the bathroom whenever there are chores to be done and disappears into the bedroom whenever I’m trying to get out the door.

I tried not waking him up once and he slept from 9pm until 4pm the next day.
