The etymology and origin of the word "occult" has more to do with its connection to terms such as "hidden" or "secret" than it necessarily does with any such supernatural element that occultism has been associated with today. The symbology that's often referred to in these videos has meaning in druidic or occult practices and rituals. Even something as simple and harmless as a jack o' lantern has meaning and history dating back to druidic rituals and practices. That being said, whether these symbols are being purposely placed in mainstream and conventional media as some sort of continuation and celebration of these practices and beliefs is another matter entirely.
