I don't want to die in my sleep

The other day when we went to Cameron Highland, I didn't sleep through the night because hubby said he wants to wake-up at 4 am and leave the house by 5 am. He went to bed at 11 pm and that pig of a hubby was already snoring by the time he hit the pillow. On the other hand, I was busy with work and with packing. When I finished, it is already 2 am. So what's the point of going to bed for two hours?

I stayed up and we left the house around almost 6 am. Had breakfast nearby and by then, I felt like I have woken up from my sleep.

I have this paranoia of not falling asleep on journeys. I told my friends that if I should die, I want to know how I died. I don't want to die in my sleep.
