How can you do this??

Time an alarm clock [i]just[/i] right to go off while you're having a lucid dream. If you're already lucid dreaming, you wouldn't really have awoken in a conventional sense because, well, you were already awake, and you'll simply continue being awake, just in a more complete different way.

Dont think like that buddy be thankful you got time wish I did

A thick plastic bag safely secured to your head would do the trick. You would drift off to sleep and your brain would shut down from the oxygen deprivation.

Provided there are no leaks or you don't get jolted into waking, you should never wake up again. It's probably best to combine the efforts with sleeping pills just to ensure a peaceful death
