Skulls as Halloween symbols can be found together or separate from skeletons. The skull symbol can mean death or danger. Like the skeleton, it is a reminder of human mortality and the short time we have to live.
Skulls are fun Halloween symbols, but they also remind us that we will eventually end up in the earth alone. (King Halloween).
