lie myself down inside the coffin waiting to die (if I can't get rid of the thought that I'm going to die quickly, it's pointless to behave as if we are in denial, lying in a coffin is probably the best way to face this death as peacefully as possible)
to prevent any hunger pains, swallow as many fruity flavored indigestible gums, so that I won't be able to feel any sensation of having an empty stomach
so we can help reduce the painful process of dying
if we want to make this death bed meaningful, when someone comes near your coffin, assuming that someone's heart is sufficiently softened by God, even if that someone isn't saved yet. Witness, lead them to Christ, have them pray the prayer of salvation, have God confirm that, and say something like "I can finally be at peace, knowing that you are finally saved at last" then rest in peace, and that should hopefully make a huge impact on the newly born again Christian, that was saved through your death bed witnessing
--> if the OP means "being raptures", first, learn to not have any fear of heights if possible, learn to keep your physical eyes above and resist the temptation to look down.
