Eat an item of food to regain health.

Fearing you're about to breathe your last, you pull a large juicy apple from your back pocket and bite in. The whole thing is gone in three large bites, restoring a total of 7 HP. It's not much, but you're not dead yet, just...close. You need to find some other way to regain health, because while your dream may sometimes function as a videogame, you're still bleeding, both externally and internally.
