Why does my toilet randomly sound like its running?

Running noises when no one flushes could mean a variety of things: The valve in the tank allows water to escape into the bowl. The flapper chain in the tank is too tight and prevents the valve from shutting all the way. The float in the toilet tank is set to a high mark, causing the toilet to run constantly.

What would make a toilet run periodically?
