This has an ensemble cast which becomes separated to their own homes. It is reminiscent of my experience running a massive Haunted House attraction. There are different types of entities which plague the cast. Some seem benign, others the exact opposite, malevolent, and malicious. The entities are ghostly and potentially demonic. Sequels, TV, or streaming episodes can easily be developed if so desired.
Similar jars can easily be manufactured and sold for a merchandising aspect.
