Many have tried and failed.

My favorite example of this was my roommate freshman year of college who’s one of my best friends. He had a paper to do, so he wanted me to wake him up at midnight so he could get some rest. He’s a very heavy sleeper so I said his name loudly while standing over his bed and probably shook him a few times.

My other roommates came into see what was going on, and one even went so far as to stick a pen in his ear to see if he reacted, but no dice. I should’ve gone to sleep and then fallen out of the bed, because that had a history of waking him up sometimes before impact.
