Not only humans, but other animals, insects, and even plants could be intelligent or sentient beings. On a more basic level we all have energy in common; there is an interconnection of all existing energy. Even one of the tiniest energies or beings, such as that of a bee, greatly affects the energy of our universe as a whole.
This series is inspired by a woman who took an injured bumblebee into her home. The bee displayed human-like qualities, appearing joyful, then sleeping in her hand, showing trust and perhaps affection.
