Deep sleepers, how do you wake up in the morning for work? Or for something else that usually requires an alarm?

Usually someone in the house wakes up hearing my alarm and they come in to wake me up

It’s actually bad how much of a deep sleeper I am, like there was two fighter jets had went to get alongside a plane in the uk and the hit a sonic boom above my house everybody was talking about it and I wasn’t aware it had even occurred because I slept through it
