I found this glitch where if I jump onto a bed, then bounce, and click it at the right time, I do take fall damage, but when I wake up, I'm dead. The player might had have a heart attack. I did this on 1 heart (2 health points)

How to die by waking up from bed:

1. Type /time set night
2. Jump from ~50 block onto bed
3. As you hit the bed, you will take 18 damage
4. You will bounce from the bed
5. Click on the bed before hitting it 2nd time
6. As you start to sleep, you will hear Something trips sound
7. Wake up
8. You will see this screen saying “You Died! <player> fell from a high place”.
