Spawn

Your Spawn Point is where you go when you die, or when you use the Magic Mirror. After creating a map, your spawn point will be in the middle of the map, on the surface. After you've made a bed, placed it, and set your spawn point, your spawn will change to wherever you placed the bed. It is very useful to make your house over your initial spawn point, because if you die, or your bed was obstructed, you will spawn inside your house. Any blocks placed at the original spawn point, including Water and Lava, are broken so the player can spawn correctly.
