If you can imagine tasting the food before you eat it. If you can imagine the drink before you drink it, or the smell of the flowers before you breath the air that surrounds them.
If you can imagine the cold before you step out, the rain before you get wet, the heat before you sweat.
If you can imagine your dreams at night before you sleep. Your actions during the day before you act them out, choices you might make outcomes they may bring.
If you can imagine your most recent memories and most distant thoughts, if you can sort them all in your head; crying at the sad and laughing at the good.
If you can imagine this then you can imagine death.
